  • Look Inside

A case with cavernous angioma at the left cerebral peduncle was cured surgically.

A 36-year-old male was admitted with complaints of right facial palsy, right motor disturbance and cheiro-oral syndrome. CT revealed a round high-density mass in the left cerebral peduncle and thalamus. Angiography showed no abnormality. MRI showed a round high-intensity mass on TI- and T2- weighted image in the left thalamus, which meant hematoma at a subacute stage and mixed-intensity core in the left cerebral peduncle, which was cavernous angioma. Symptoms disappeared, and high-density also disappeared gradually, but rebleed-ing occurred. Because of this, an operation was per-formed by the orbitofrontmalar approach. Hematoma and angioma were removed under ABR and SEP moni-tor, which showed no abnormality during the operation. Histological examination of the surgical specimen re-vealed that the abnormal vessels were cavernous angioma.

The postoperative course was uneventful without cosmetic problems.
