Rosai-Dorfman disease mimicking a sphenoid wing meningioma.
A 40-year-old male presented with a single generalized tonic-clonic seizure. MRI revealed an enhancing, dural-based, left lateral sphenoid wing lesion suggestive of a meningioma. At microsurgical excision, the lesion was firm and relatively avascular. The histopathological report revealed S-100 positive histiocytic proliferation with lymphophagocytosis (emperipolesis) characteristic of the Rosai-Dorfman disease. The case and its management are discussed.
