title: [Intracranial neurinoma of the jugular foramen-a case report (author's transl)].
abstract: This report is a case of intracranial neurinoma of the jugular foramen. A 21-year-old woman was admitted to our hospital with complaints of headache, nausea, tinnitus on the left and deafness on the left. The neurological examination revelaed bilateral choked disc, Bruns Cushing nystagmus, hearing disturbance on the left, slight disturbance of vestibular function on the left, diminished gag reflex on the left, curtain sign on the left, loss of taste on the posterior third of the left side of the tongue, and deviation of the tongue to the left on protrusion, accompanied with atrophy and fasciculation on the left. Skull-XP showed the enlargement of the jugular foramen. Pneumoencephalogram showed the enlargement of the fourth ventricle combined with the superior, posterior displacement of it's floor. We confirmed the diagnosis of the jugular foramen neurinoma on the left. By suboccipital craniectomy a walnutsized tumor was disclosed at the jugular foramen. The tumor was encapsuled with smooth, thick capsule and was colored in dark rouge. This tumor was removed totally and the postoperative course was uneventful. The pathological diagnosis was neurinoma. We consider that this tumor originated in the ninth or tenth cranial nerve.
