[Surgical excision of a cavernous angioma of the cerebral peduncle by orbito-fronto-malar approach].
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 T1-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 rebleeding occurred. Because of this, an operation was performed by the orbitofrontmalar approach. Hematoma and angioma were removed under ABR and SEP monitor, which showed no abnormality during the operation. Histological examination of the surgical specimen revealed that the abnormal vessels were cavernous angioma. The postoperative course was uneventful without cosmetic problems.
