Isolated Intracranial Rosai-Dorfman Disease Mimicking a Meningioma

Abstract

Rosai-Dorfman disease (RDD) is a rare idiopathic his to proliferative disorder that usually presents with systemic symptoms and cervical lymphadenopathy. Intracranial involvement is relatively rare and isolated intracranial RDD is very scarce. It resembles meningioma on imaging scans and is difficult to differentiate preoperatively. We present our case of isolated intracranial RDD in 25 years-old man that mimicked a meningioma on imaging.
