Case ReportsCavernous angioma in the fourth ventricular floor--case report.
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. ⋯ Postoperatively, ataxic gait, nausea, and vomiting disappeared gradually. MR imaging was useful to accurately evaluate the anatomic relationship between the lesion and the brainstem.
