Cavernous angioma associated with venous angioma--two case reports.

A 17-year-old male and a 28-year-old female presented with cavernous angioma and venous angioma colocated in the same region, and manifesting as convulsions. The cavernous angiomas were extirpated without damage to the venous angioma. No postoperative neurological deficits were observed. The patients have been free of convulsions without anticonvulsant medication for 2 years. Early extirpation of cavernous angioma with presentation of venous angioma is recommended, preferably before bleeding occurs.
