title: Neuroma of the cavernous sinus.
abstract: A case of a surgically verified parasellar neuroma is presented. Despite clinical and radiological evidence for the origin of the tumor to be the trochlear or oculomotor nerves, an operation revealed a neuroma originating from the cavernous sinus, but exact identification of the origin of the tumor was not possible. The radiologic findings including polytomography, angiography and computed tomography are presented. The clinical and radiological differentiation between this case and typical neuromas of the gasserian ganglion are discussed.
