自MRI问世,偶然发现大脑静脉血管瘤(VA)增多,但未见报道多发性者。作者用1.5T MR检查58例VA。男25例,女33例,年龄1～76岁,平均40岁。除9例出血外,大多数VA者无症状。58例中33例还作了增强,29例作了选择性血管成像。结果见到,58例中MRI显示63个VA(5例各有2个),呈穿越大脑的线样结构(引流静脉),有或无扩张的髓 Since the advent of MRI, incidental aneurysms of cerebral venous hemangioma (VA) have been found incidentally, but no recurrent multiple reported. The authors examined 58 cases of VA with 1.5T MR. 25 males and 33 females, aged 1 to 76 years old, average 40 years old. In addition to the bleeding in 9 cases, most VA were asymptomatic. Thirty-three of the 58 patients also had an enhancement and 29 had selective angiography. The results showed that in 58 cases, MRI showed 63 VA (2 in 5 cases), a linear pattern of traversing the brain (draining veins) with or without dilatation of the medulla
