总结8例经组织学证实的血管造影隐匿性脑动静脉畸形患者进行了普通和灌注计算机断层扫描（CT）检查。在5例血管造影显示一个低血供肿块，在3例血管造影是正常的。CT检查显示高密度病变（6例）和心室不对称（5例）。在3例脑出血患者中，高密度表现和脑室受压是由于血肿的存在。5例癫痫患者中，3例伴钙化灶，1例同侧和1例对侧脑室增大。在8例中的5例中，灌注CT扫描的血管增强提示病变的血管性质。脑胶质瘤是一种常见的误诊。
SUMMARY Eight patients with a histologically proven angiographically occult arteriovenous malformation of the brain had plain and infused computed tomographic (CT) examinations. In five cases angiography revealed a hypovascular mass and in three cases the angiogram was normal. On CT examination a high density lesion (six cases) and ventricular asymmetry (five cases) were demonstrated. In three patients presenting with intracerebral hemorrhage, the high density appearance and ventricular compression were accounted for by the presence of hematoma. In three of five seizure patients the high density lesion was associated with calcification while ipsilateral (one case) and contralateral (one case) enlargement of the lateral ventricle was seen. In five of the eight cases the vascular nature of the lesion was suggested by vascular enhancement of the infused CT scan. Glioma was a common misdiagnosis.
