Meningioma of the lateral cerebral ventricle. A case report.

The authors present the case of a 58-year-old woman. At presentation the patient complained of vertigo and noise in the ears with six months history, and from headache, accompanied by nausea and vomiting from three months. The physical examination of the patient found no abnormalities. The neurological examination revealed discoordination syndrome and mild hemiparesis of the left limbs. Computed tomography of the brain without and with contrast medium showed oval tumor, localized in the region of trigonum collaterale and the posterior horn of the right lateral ventricle. Operative intervention was performed after a preoperative management of the patient: transcortical fenestration of the brain in the region of trigonum collaterale and the posterior horn of the right lateral ventricle. The tumor was totally removed. It is well isolated, oval in shape, with feeding blood vessel from plexus chorioideus and was attached to the wall of the ventricle with several thin bridges. Macroscopically the tumor was 3 cm in diameter, with smooth walls, well capsulated, grey-brownish in color and with firm elastic consistence. The histological findings revealed meningioma--meningotheliomatose variant.
