title: Tentorial schwannoma mimicking meningioma.
abstract: A 58-year-old woman presented with a rare tentorial schwannoma manifesting as a chief complaint of headache. Magnetic resonance imaging showed an infratentorial extra-axial mass lesion with both cystic and solid components and dural tail sign. The tumor was easily separated from the surrounding structures, and the origin was apparently the tentorial branch of the trigeminal nerve. Tentorial schwannoma should be considered in the differential diagnosis of mixed cystic and solid mass lesions associated with the tentorium around the ambient cistern.
