title: Intracerebral venous angioma.
abstract: Intracerebral venous angioma is a rare congenital vascular malformation of the brain. Three cases are reported, all of which had strikingly similar angiographic findings in the venous phase, viz., a local network of small medullary veins which converge centrally into a single large venous channel which courses transcerebrally to reach the superficial venous system. No gross abnormalities are seen in the arterial phase with the usual techniques. However, magnification delineated enlarged arterial branches supplying the periphery of the malformation in 2 of the 3 cases. A poorly marginated homogeneous blush and early filling of the draining veins were also seen in these 2 patients. The findings in the venous phase agree with those described in previous isolated case reports and appear to be highly suggestive of this rare malformation.
