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.
脑静脉血管瘤是一种罕见的先天性脑内血管畸形。本文报告了3例病例，所有病例在静脉期均有极为相似的血管造影表现，即局部小髓静脉网络向中央汇聚成一条大静脉通道，该通道经脑内走行至浅表静脉系统。采用常规技术在动脉期未见明显异常。然而，放大造影显示3例中的2例有供应畸形周边的动脉分支增粗。这2例患者还可见边界不清的均匀染色及引流静脉早期显影。静脉期的表现与以往孤立病例报告中所描述的一致，似乎高度提示这种罕见的畸形。
