title: [A case of microsurgically removed cavernous angioma in the midbrain].
abstract: The authors presented a case of microsurgically removed large cavernous angioma in the midbrain. A 46-year old woman was admitted to our service with bilateral nuclear oculomotor pareses and mild tetraparesis. MRI revealed a large round well-circumscribed high signal-intensity lesion on both T1 and T2 weighted image with low signal rim in the midbrain. This lesion was diagnosed preoperatively as a cavernous angioma. The operation was performed in three steps with intermittent hemorrhages by interhemispheric transcallosal-hippocampal commissure--velum interpositum-third ventricular approach and subsequent two infratentorial supracerebellar approaches and finally complete removal was performed. Histological examination of the surgical specimen revealed as a cavernous angioma having abnormal vessels with honeycomb appearance. The patient survived, although remains moderately disabled 6 months after the last operation.
