Magnetic resonance imaging and trigeminal schwannoma. 1987

D Rigamonti, and R F Spetzler, and A Shetter, and B P Drayer

A case of trigeminal schwannoma, extending from the posterior fossa into Meckel's cave, is reported. The information provided by computed tomography, angiography, and magnetic resonance imaging allowed a correct preoperative diagnosis to be obtained. Due to the excellent sensitivity, the absence of bone artifacts, and the ease of imaging in any plane, magnetic resonance imaging best defined the "dumbbell" nature of the tumor, the atrophy of the masticatory muscles, and the infiltration of the third division of the trigeminal nerve.

UI MeSH Term Description Entries
D009442 Neurilemmoma A neoplasm that arises from SCHWANN CELLS of the cranial, peripheral, and autonomic nerves. Clinically, these tumors may present as a cranial neuropathy, abdominal or soft tissue mass, intracranial lesion, or with spinal cord compression. Histologically, these tumors are encapsulated, highly vascular, and composed of a homogenous pattern of biphasic fusiform-shaped cells that may have a palisaded appearance.

D014276 Trigeminal Nerve The 5th and largest cranial nerve. The trigeminal nerve is a mixed motor and sensory nerve. The larger sensory part forms the ophthalmic, mandibular, and maxillary nerves which carry afferents sensitive to external or internal stimuli from the skin, muscles, and joints of the face and mouth and from the teeth. Most of these fibers originate from cells of the TRIGEMINAL GANGLION and project to the TRIGEMINAL NUCLEUS of the brain stem. The smaller motor part arises from the brain stem trigeminal motor nucleus and innervates the muscles of mastication.
