[Concurrent cavernous and venous cerebral angiomas].
Presence of venous angioma (VA) in a close vicinity of cavernous angioma (CA) of the brain enhances the risk of bleeding from CA. However, VA drains the venous blood from surrounding brain tissue and should be left in place during surgical removal of CA. Coincidence of CA and VA was found in 6 of 44 patients operated on for 45 CA during a six years period (1993-1998). Coincidental VA were found more often with the CA located in the deep structures of the brain, in the thalamus and the brainstem (5 of 15 cases) than with the superficial CA (1 of 30 cases). The most valuable diagnostic method was T1 weighted MR imaging with contrast enhancement, less reliable was nonenhanced T1 or proton density weighted imaging. Finding of the VA may positively influence the decision making concerning the indication for surgery and the selection of the most appropriate surgical tactics. (Tab. 1, Fig. 2, Ref. 15.)
