めまいを主訴とした小脳海綿状血管腫に静脈性血管腫を合併した一例

抄録

A 40-year-old male patient had a vertigo attack with vomiting; however, there was no hearing loss, headache, or palsy of arms or legs. On admission, the CT examination did not show any tumors, or infarctions of the brain, brain stem or cerebrum. Neurotological findings of an electro-nystagmography and caloric test did not show any abnormalities, except a platform test showed positive. Two days after admission, MRI examination showed a small mass (15 mm) in the left cerebellar peduncle. Previously, cavernous anginoma was considered rare, but the increasing use of MRI has demonstrated numerous cases. Typically, epileptic or other convulsive symptoms appear initially, but in our case, pathology was indicated by vertigo without other cranial nerve symptoms.
