Background: Rosai-Dorfman disease (RDD) is typically characterized by painless bilateral and symmetrical cervical lymphadenopathy, with associated fever and leukocytosis. The aim of the current study was to summarize the clinical features and imaging characteristics of RDD, in an effort to improve its diagnostic accuracy.
Methods: The study was analyzed from 32 patients between January 2011 and December 2017; of these, 16 patients had pathologically diagnosed RDD, eight had pathologically diagnosed meningioma, and eight pathologically diagnosed lymphoma. All patients underwent computed tomography and magnetic resonance imaging (MRI). Clinical features and imaging characteristics of RDD were analyzed retrospectively. The mean apparent diffusion coefficient (ADC) values of lesions at different sites were measured, and one-way analysis of variance and the least significant difference t-test were used to compare the differences between groups and draw receiver operating characteristic curves. The tumors were excised for biopsy and analyzed using immunohistochemistry.
Results: The mean ADCs were (0.81 ± 0.10) × 10−3 mm2/s for intercranial RDD, (0.73 ± 0.05) × 10−3 mm2/s for nasopharyngeal RDD, (0.74 ± 0.11) × 10−3 mm2/s for bone RDD, and (0.71 ± 0.04) × 10−3 mm2/s for soft-tissue RDD. The optimum ADC to distinguish intracranial RDD from lymphoma was 0.79 × 10−3 mm2/s (62.5% sensitivity and 100% specificity) and to distinguish meningioma from intracranial RDD was 0.92 × 10−3 mm2/s (62.5% sensitivity and 100% specificity). Levels of C-reactive protein, erythrocyte sediment rate and D-dimer were significantly elevated (81%, 87%, and 75%, respectively). On immunohistochemistry, RDD was positive for both S-100 and CD68 proteins but negative for CD1a.
Conclusions: Conventional MRI, combined with diffusion-weighted imaging and ADC mapping, is an important diagnostic tool in evaluating RDD patients. An accurate diagnosis of RDD should consider the clinical features, imaging characteristics, and the pathological findings.

| Introduction|| |
Rosai-Dorfman disease (RDD) is a rare form idiopathic non-Langerhans cell histiocytosis, also known as sinus histiocytosis with massive lymphadenopathy. RDD clinically manifests as painless, massive cervical lymphadenopathy, with associated fever, weight loss, and polyclonal hypergammaglobulinemia. Although originally described as a nodal disorder, extranodal disease has occurred in up to 40% of cases, with disease sites including the skin, central nervous system, upper respiratory tract, orbit and eyelid, and gastrointestinal tract. This rare disease demonstrates predominance in young adults, although cases in older adult have been documented.
The etiology and pathogenesis of RDD are currently unknown, and the disease can easily be misdiagnosed. In this study, we analyzed 16 cases of RDD confirmed by pathology, summarized the patients' clinical and imaging features, and reviewed the relevant literatures. The aim of this study was to use clinical and imaging features to improve the diagnostic accuracy of RDD.
| Methods|| |
The study was conducted in accordance with the Declaration of Helsinki and was approved by the Ethical Committee of TheFirst Affiliated Hospital of Zhengzhou University. All patients gave informed consent for the present study.
We retrospectively analyzed the medical records of 32 patients who were treated with definitive surgery at our hospital from January 2011 to December 2017. Of these, 16 patients had pathologically diagnosed RDD, eight patients with pathologically diagnosed meningioma, and eight patients with pathologically diagnosed lymphoma which were located in brain. All patients underwent surgery for total or subtotal resection of tumors. None of the patients underwent radio- or chemo-therapy postoperatively. Patients were followed up after the surgery between 1 and 24 months.
All patients underwent computed tomography (CT, Discovery, 750HD, General Electric Company, America) and magnetic resonance imaging (MRI, 3.0T magnetic resonance scanner, Skyro, Siemens, Germany) scanning with the fast low angle shot 2D sequence T1-weighted (repetition time [TR] 250ms, echo time [TE] 2.5 ms) in the sagittal plane and cross-sectional scanning; and the turbo spin echo (SE) sequence T2-weighted imaging (TR 4500 ms, TE 100 ms) in the cross-sectional plane, a layer thickness 5 mm, no spacing interval, and two excitation imaging. On axial diffusion-weighted imaging (DWI), a SE echo planar imaging sequence was used with TR 3700 ms and TE 102 ms, b-values of 0 and 1000, a layer thickness of 5 mm, layer spacing 1.8 mm, and a matrix field of view of 219 mm × 219 mm. The apparent diffusion coefficient (ADC) map was generated automatically. During enhanced scanning, patients were injected with contrast agent (gadopentetate dimeglumine [Beijing Beilu Pharmaceutical Co., China]) at a dose of 0.2 ml/kg.
To obtain ADC values, multiple small circular regions of interest (ROIs) measuring 10–20 voxels (7–15 mm 2) were manually delineated on the pretreatment ADC map that was created using Syngo workstation (Siemens, Germany). All ROIs were drawn by radiologists blinded to patient outcomes and corresponded to T2-weighted, enhanced T1-weighted, and DWI images. Radiologists meticulously avoided areas of cystic change, necrosis, or hemorrhage and selecting the mean ADC at the maximum level of the lesion, took measurements three times, and calculated the mean value of three ADCs.
Erythrocyte sediment rate (ESR), C-reactive protein (CRP), and D-dimer levels were assayed in all patients. Postoperative specimens were stained with hematoxylin and eosin and immunohistochemical staining to detect antibodies for CD1a, S-100 protein, and CD68.
SPSS 20.0 (IBM Corporation Inc., Armonk, NY, USA) was used for statistical analysis. ADC values were expressed as means ± standard deviations (SD). If the data were in normal distributions, comparisons were assessed with the Student's t-test between intracranial and other parts RDD. One-way analysis of variance (ANOVA) was used to compare differences between the mean ADC values for intracranial RDD, meningioma, and lymphoma. A value of P < 0.05 was considered statistically significant. The least significant difference t-test was also used to compare between the two groups and a receiver operating characteristic (ROC) curve was drawn. The Youden index ([sensitivity + specificity] −1) estimated threshold value of ADC values.

Clinical and laboratory examination
The 16 participants included eight women and eight men who were aged between 1 and 63 years (mean age, 37.9 ± 20.6 years). Of the 16 patients, five cases of lesions located in the cerebrum and three in the cerebellum, which manifested as headache and dizziness. Of four cases were located in the nasopharynx and neck, which mainly manifested as progressive painless swelling. Of one case was located in the thigh bone, two case was located in the ribs, and one case was located in the hip, which mainly manifested as pains of the lesion. After surgery and during the follow-up period, lesions recurred in one patient. Clinical data of the 16 patients are summarized in [Table 1]. The levels of CRP were significantly elevated (33.78 ± 46.44 mg/L) in 13 patients (81%) and the ESR elevated (34.44 ± 26.18 mm/h) in 14 patients (87%). Furthermore, D-dimer levels were slightly elevated (0.56 ± 0.65 μg/ml) in 12 patients (75%).
Of the intracranial lesions [patient 2, [Figure 1] of patients 1–8, CT imaging showed that the lesions had a slightly hyperdense and a nonuniform enhancement. MRI revealed a heterogeneous T1-weighted signal, and a hyperintensity mixed with hypointensity signal on T2-weighted images. In addition, edema was detected around the lesions and manifested as hypointensity within an area of hyperintensity on the T2 dark fluid sequence. DWI showed that lesions were diffusion limited. There was heterogeneous enhancement of lesions on dynamic contrast enhancement imaging.

For the lesions located in the nasopharynx and neck of patients 9–12, CT imaging indicated that the lesions were soft-tissue masses. The boundaries of the lesions were not clearly delineated on CT imaging and the lesions showed nonuniform signal enhancement. MRI showed that these lesions had hyperintensity on T1-weighted, and a hyperintensity mixed with hypointensity on T2-weighted, nonuniform enhancement, and the bone adjacent to the nasopharynx was not destroyed [patient 9, [Figure 2].

For lesions located in the bone of patients 13–15, soft-tissue lesions were found adjacent to bones of patients 13–15. CT imaging showed isodense or hyperdense soft-tissue masses, with associated osteolytic destruction. On CT contrast enhancement, the lesion showed slightly irregular in homogeneous enhancement. MRI revealed multiple bone lesions with hypointensity on T1- and hyperintensity on T2-weighted images and with strong enhancement after injection of gadolinium contrast agent.
For the lesions located in the hip of patient 16, MRI showed the lesions as irregular and cystic, with a heterogeneous hyperintensity on T1- and T2-weighted. On fat-suppression T1 sequence, the lesions showed high signal. DWI revealed the lesions to be diffusion restricted. On dynamic contrast enhancement, the capsule wall of the lesion showed slight reinforcement, with no reinforcement of the cystic cavity [patient 16, [Figure 3].

The mean ADC value of intracranial RDD was (0.81 ± 0.10) × 10−3 mm 2/s. Within the head, malignant lymphomas had a mean ADC value of (0.61 ± 0.12) × 10−3 mm 2 and meningomas was (0.94 ± 0.11) × 10−3 mm 2. A ROC curve was drawn based on the mean ADC value of patients [Figure 4]. The optimum ADC to distinguish meningoma from intracranial RDD was 0.92 × 10−3 mm 2/s (62.5% sensitivity and 100% specificity), and the area under the ROC curve (AUROC) was 0.813. The optimum ADC to distinguish intracranial RDD from malignant lymphomas was 0.79 × 10−3 mm 2/s (62.5% sensitivity and 100% specificity), and the AUROC was 0.859. The mean ADC values of RDD located in nasopharynx and neck, bone, and soft tissue were (0.73 ± 0.05) × 10−3 mm 2/s, (0.74 ± 0.11) × 10−3 mm 2/s, and (0.71 ± 0.04) × 10−3 mm 2/s, respectively. There is no difference between the ADC values of intracranial RDD and other parts RDD [Table 2].

Patients underwent excisional biopsy followed by pathological examination of excised tissue. Tissue samples were grayish-red or grayish-yellow in appearance and contained large, pale histiocytes with vacuolated eosinophilic cytoplasm, mixed with scattered plasma cells, and mature lymphocytes. Emperipolesis, consisting of histiocytes engulfed in well-preserved lymphocytes, was observed in the permanent paraffin-embedded tissues [patient 4, [Figure 5]. Immunohistochemical analysis showed that the masses were positive for S-100 and CD68 proteins but negative on CD1a staining.

Overview of Rosai-Dorfman disease
RDD is an extremely rare nonmalignant histiocytic disorder. Usually, patients present with painless swollen cervical lymph nodes. Extranodal involvement is common and may occur in more than 40% of patients, sometimes without associated lymphadenopathy. The most frequent affected extranodal sites include the skin and soft tissue (17%); the nasal cavity and paranasal sinuses (16%); the eye, orbit, and ocular adnexa (11%); the bone (1l%); the salivary gland (7%); the central nervous system (7%); the oral cavity (4%); the kidney and genitourinary tract (3%); the respiratory tract (3%); the liver (1%); the tonsil (1%); the breast (, RDD is usually more common in children and adolescents although RDD located in the skin and intracranial is more common in middle-aged and elderly people. Only three of the 16 cases in this study occurred in adolescents, the median age of patients was 37.94 ± 20.56 years. The precise causative mechanism of RDD remains unknown, but immune system dyscrasias and viral infections, specifically human herpesvirus 6, have been implicated in the previous study. Moreover, current evidence suggested a possible role for SLC29A3 mutations in familial RDD.
Imaging manifestations of Rosai-Dorfman disease
In this article, we have summarized the clinical and imaging features of RDD lesions located in the head, neck, bone, and hip. Intracranial RDD usually occurs without extracranial lymphadenopathy, and most intracranial lesions are attached to the dura such as the convex surface of the brain, the saddle area, the middle cranial cavity, the sagittal, and the cavernous sinus, with only few cases extending into the parenchyma. Common signs include cephalgia, seizure, weakness of limbs, and cranial nerve deficiency, depending on the location of the lesion. Intracranial RDD is usually visualized as a mixed isointense or hyperintense mass on T1-weighted MRI, with distinct borders and heterogeneous contrast enhancement. On T2-weighted images, the lesions usually presented heterogeneous hyperintense signals and sometimes hypointense signals. Some studies have postulated that the aggregation of hypointense signals on T2-weighted images is a characteristic manifestation of RDD and may be related to free radicals released by macrophages during phagocytosis., However, in the study, only one patient presented with aggregation of hypointense signals on T2-weighted images, and lesions usually had minimal contrast enhancement. Meningiomas usually have an isointense signal on T1-weighted MRI, a hypointense signal on T2-weighted MRI, and homogeneous enhancement on dynamic contrast enhancement images. In this study, intracranial lesions had a slightly high density and nonuniform enhancement on CT imaging. In addition, the presentation on MRI was consistent with that in previous studies. Magnetic resonance spectroscopy (MRS) has particular specificity for some patients. In meningiomas, the proton spectrum indicated that the alanine spectrum was significantly elevated, and its peak was 48 ppm, while in intracranial RDD, the spectrum indicated that the choline peak was 140 ppm, which can distinguish from meningioma. Therefore, MRI combined with MRS might be a useful method of diagnosing RDD and meningiomas.
The lesions of four patients were located in the nasopharynx, which is the disease site with the second highest occurrence rate of extranodal RDD. Nasopharyngeal RDD was mostly located in the maxillary sinus. RDD located in nasal cavity and nasopharynx manifest as diffuse mucosa thickening and invades the nasal dorsum and subcutaneous tissues. Moreover, this type of RDD can also manifest as polypoid and soft-tissue masses, along with invasion and deterioration of sclerotin, or as a proliferating cirrhosis of the sinusoidal wall. These lesions typically showed uneven enhancement on dynamic contrast enhancement scans. In the present finding, four nasopharyngeal RDD were of the soft-tissue type, which showed a uniform density on CT and MRI scans and did not invade the sclerotin of the nasopharynx, which were consistent with previous studies. Nasopharyngeal RDD needs to be distinguished from nasal polyps and squamous cell carcinoma of the nasopharynx. Nasal polyps are usually located in the middle nasal meatus, and enhanced MRI scans show a manifestation in the polyp mucosa, which are often obscured by the bone around the nasopharynx. Squamous cell carcinoma of the nasopharynx is an invasive growth, with nonuniform density and necrosis commonly found in the cervical lymph nodes. In addition, imaging manifestations combined with laboratory and pathological examination might be helpful for diagnosing RDD.
Bone involvement is a rare manifestation of RDD occurring in approximately 10% of RDD cases and with a balanced sex distribution. Wei et al. have reported that bone RDD is often located in bones including the long bones, craninal bones, fingers, and phalanges. Bone lesions in RDD are primarily osteolytic on conventional radiographic imaging, with some lesions also showing sclerotic margins. Symptoms typically include pain and swelling. In this study, three patients presented with RDD in bone. CT showed osteolytic changes in these three patients, consistent with descriptions in the literature. Bone RDD is usually misdiagnosed as chronic, nonspecific inflammatory changes, tuberculosis, or other cancers and relies on postoperative pathological examination for the correct diagnosis.
Soft-tissue RDD (STRDD) is rare, with sporadic cases previously reported in no more than 3% of RDD patients. The female : male ratio of STRDD cases is approximately 3:1. STRDD is also characterized by a broad tumor size range and a wide patient age range. A study by Al-Daraji et al. reported that multifocal STRDD was much more prone to recurrence. There is no difference in STRDD recurrence rates between men and women, possibly due to low incidence of the disease. We identified one patient with STRDD; this patient had an isolated mass on the hip but no signs of recurrence during 13 months of follow-up. Imaging examinations such as CT and MRI were useful for evaluating the extent of STRDD, although there were no specific characteristics.
DWI is an MRI technique based on measuring water diffusion in tissues. This diffusion can be quantified by ADC. According to the literature, ADC values can be used to discriminate between malignant and benign lesions; typically, malignant tumors have lower values than benign lesions. RDD shows high signal-restricted diffusion on DWI. In this study, malignant lymphomas in the head had a mean ADC value of (0.61 ± 0.12)× 10−3 mm 2/s and meningomas of (0.94 ± 0.11 )× 10−3 mm 2/s, while intracranial RDD had a mean ADC value of (0.81 ± 0.10) × 10−3 mm 2/s. In this report, the mean ADC values of RDD located in nasopharyngeal, bone, and soft tissue were (0.73 ± 0.05) × 10−3 mm 2/s, (0.74 ± 0.11) × 10−3 mm 2/s, (0.71 ± 0.04) × 10−3 mm 2/s, respectively. The ADC value of intracranial RDD was no statistically significant compared with RDD located in other parts (nasopharyngeal, bone, and soft tissue). The ADC value is associated with several histopathological features. It has been shown that there is an inverse correlation between the ADC and cell count of lesions. The mean ADC value of intracranial RDD was higher than that of lymphomas but lower than that of meningiomas in the study, possibly due to the cellular structure of RDD. The mechanism of RDD might involve infiltration of small neoplastic cells, such as those of malignant lymphomas, which disrupt the movement of water molecules, resulting in vasogenic edema, destruction of brain tissue, or infiltration of large cells. Microscopic examination of RDD lesions reveals plasma cells, lymphocytes, and large histiocytes within a dense collagenous background. On histopathological examination, plasma cells are numerous, often arranged along small blood vessels. This might explain the low ADC values of RDD. In conclusion, conventional MRI combined with DWI might help to determine the activity of RDD and to evaluate patients with the disease.
Histopathology of Rosai-Dorfman disease
Diagnosis of RDD is usually confirmed on pathological examination. Noguchi et al. reported that some patients with RDD had a slight elevated of CRP and ESR; in addition, there may be nonspecific increases in other laboratory parameters in cases of RDD, according to another study. However, in this study, we found that D-dimer levels increased in twelve patients. Specimens are typically obtained by an open surgical biopsy or fine-needle aspiration. In general, histopathological analysis shows a large number of mixed-cell populations, including mature plasma cells and lymphocytes. The most commonly detected cells are histiocytes with an accentuated phagocytic appearance. The infiltration of these inflammatory cells might be related to the increase in D-dimer levels. These histiocytes harbor apparently intact lymphocytes, lending the appearance of a “cell within a cell,” or emperipolesis. Emperipolesis is not a unique phenomenon to RDD and has been seen in both normal and leukemic processes. On immunohistochemical staining, RDD histiocytes were positive for CD68, CD14, HLA-DR, fascin, CD163, and S-100, but typically negative for CD1a, enabling the disease to be distinguishing from Langerhans histiocytosis. The differential diagnosis of RDD includes histiocytosis of Langerhans cells, histiocytic sarcoma, lysosomal storage diseases (e.g., Gaucher disease), classical Hodgkin lymphoma, melanoma and metastatic carcinomas, and infections involving the lymph nodes caused by histoplasma and mycobacteria. Pathology and laboratory examinations are an effective means of distinguishing RDD from other diseases.
Treatment of Rosai-Dorfman disease
Most patients with RDD experience a chronic disease course. Due to its low incidence, no optimal or standard treatment has been defined. The disease is often self-limiting with a very good outcome; nevertheless, 5–11% of patients die from this disease. Treatment strategies can vary according to the severity of vital organ involvement. Primarily, patients undergo surgery or receive glucocorticoids. Systemic corticosteroids are usually helpful in decreasing nodal size and symptoms; however, they can be immunosuppressive, with possible RDD recurrence after a short period of interruption. Chemotherapy for the treatment of RDD has shown controversial results. Methotrexate and 6-mercaptopurine have shown potential for efficacy and requires further investigation. Another report have suggested using alpha-interferon, although its side effects have limited its use. Anti-CD20 monoclonal antibody/rituximab has been described in one case. In addition to chemotherapy, the role of radiotherapy for RDD is not well understood. Some reports have described a full resolution of RDD with treatment by radiotherapy, whereas others have shown no response.
We analyzed 16 cases of RDD confirmed by pathology, and summarized the patients' clinical and imaging features. ESR, CRP, and D-dimer of RDD patients were increased. Only one patient of RDD manifested the aggregation of hypointense within hyperintense on T2-weighted. RDD showed high signal and diffusion restricted on DWI; a low ADC value. The ADC value is useful for distinguishing intracranial RDD, meningioma, and lymphoma. Conventional MRI combined with DWI might help to determine the activity of disease and to evaluate patients with RDD. However, this study had some limitations. The sample size was small, particularly for patients with nasopharyngeal, bone, and STRDD. Further studies with larger samples are therefore needed. In conclusion, the accurate diagnosis of RDD should consider the clinical features, imaging characteristics, and the pathological findings.
