Two patients with surgically-excised brain-stem cavernous angioma are reported on. Direct operation was indicated because the angiomas exhibited recurrent hemorrhage and were located adjacent to the cisterns. Both showed postoperative transient deterioration of neurological deficits, which improved several weeks after the procedures. The angioma located at the right cerebral peduncle was totally excised, whereas that at the dorsal pons remained and rebled. Brain-stem cavernous angiomas adjacent to cisterns or to the venrticles should be surgically excised when they exhibit recurrent hemorrhange. Total excision of the lesion with minimal damage to the intact brain is especially required in the direct surgery of the brain-stem cavernous angioma.
