title: Primary malignant schwannoma of the Gasserian ganglion. Report of two cases.
abstract: The diagnosis, radiographic features, clinical presentation, and treatment of two cases of primary malignant schwannoma of the Gasserian ganglion are discussed. Radiographic differentiation from trigeminal neurinoma is not possible; however, erosion of the foramina favors a diagnosis of malignancy. Radiation therapy was successful in the management of both cases and is recommended for extensive lesions.
