rare presentation of rosai-dorfman syndrome: first reported case in Iran

A case of intracranial Rosai-Dorfman syndrome is presented that was initially diagnosed and treated as meningioma, and was complicated due to a wrong diagnosis of coexistent lung sarcoidosis. Intracranial lesions appeared as dura-based parasellar and anterior fossa enhanc-ing lesions on magnetic resonance images. Excellent result was obtained from whole brain radiotherapy, which can be used as a guideline for treating similar cases
