In this report, we describe 2 cases of rare intracranial extranodal Rosai-Dorfman disease. The occurrence of this type of non-Langerhans cell histiocytosis in the central nervous system is infrequent, with less than 5% of cases. The first patient was a 35-year-old male who presented with recurring headaches, and the second patient was a 50-year-old male who reported sudden onset of dizziness and vomiting. Computed tomography scans were performed in both cases, but magnetic resonance imaging played a crucial role in the characterization of the lesions and their locations in the thalamus, third ventricle, lateral ventricles, and cerebellopontine angle area. The final diagnosis was confirmed through pathological examination and immunohistochemistry following brain tumor resection. These cases underscore the significance of magnetic resonance imaging in the early diagnosis of intracranial extranodal Rosai-Dorfman disease.
在本报告中，我们描述了2例罕见的颅内结外Rosai-Dorfman病。这种类型的非朗格汉斯细胞组织细胞增生症在中枢神经系统中并不常见，病例占比不到5%。首例患者为一名35岁男性，表现为反复头痛，第二例患者为一名50岁男性，报告突然出现头晕和呕吐。两例患者均进行了计算机断层扫描，但磁共振成像在病变特征及其在丘脑、第三脑室、侧脑室和桥小脑角区域的定位方面发挥了关键作用。脑肿瘤切除术后通过病理检查和免疫组织化学确诊。这些病例强调了磁共振成像在颅内结外Rosai-Dorfman病早期诊断中的重要性。
