Rosai-Dorfman disease is an uncommon benign non-Langerhans cell histiocytosis proliferative disorder. It commonly involves the lymph nodes and is classically presented with massive cervical lymphadenopathy. It can also involve the extra-nodal sites of the body and is reported in 43% of Rosai-Dorfman disease cases. The central nervous system is rarely involved in Rosai-Dorfman disease from which intra-cranial is more common than spinal lesions. An isolated dural-based intra-cranial Rosai-Dorfman disease is extremely rare. It usually mimics meningioma on radiological imaging. It is very difficult to diagnose the Rosai-Dorfman disease on imaging and intra-operative appearances of the lesion. We present a histopathologically proven case of an isolated Rosai-Dorfman disease involving the central nervous system in 49 years old female patient which was radiologically mimicking the meningioma.
