Cavernous Angioma in the Fourth Ventricular Floor : Case Report

概要

論文の詳細を見る
A rare case of cavernous angioma located in the fourth ventricular floor occurred in a 44-year-old female complaining of occipital headache, vomiting, diplopia, and dysarthria. Computed tomographic scans demonstrated a high-density area in the fourth ventricle and slight hydrocephalus. Magnetic resonance (MR) imaging showed a mixed intensity mass on T_2-weighted images and high- or isointensity regions on T_1-weighted images. The tumor was totally removed and histologically diagnosed as cavernous angioma. Postoperatively, ataxic gait, nausea, and vomiting disappeared gradually. MR imaging was useful to accurately evaluate the anatomic relationship between the lesion and the brainstem.
