title: Isolated intracranial Rosai-Dorfman disease mimicking suprasellar meningioma: case report with review of the literature.
abstract: Rosai-Dorfman disease (RDD) is an idiopathic histiocytic proliferation affecting the lymph nodes. Isolated intracranial RDD is rare and usually appears as a well-defined, dural-based lesion without lymphadenopathy. The clinical and radiological features of intracranial RDD are similar to meningioma. Histopathology and immunohistochemistry are essential for a definitive diagnosis. This is a report of a 43-year old male with isolated intracranial RDD, which manifested as a suprasellar meningioma. The clinical, radiological and pathological aspects of the disease are discussed within the context of a review of previously reported cases.
