本文分析了两种脑血管畸形(33例动静脉畸形和4例海绵状血管瘤)的脑血管造影和 CT 扫描结果。根据动静脉畸形在脑血管造影和 CT 扫描的表现,将其分为五型,隐匿型、孤立型、树枝型、曲张型和动静脉瘤型。本文讨论了动静脉畸形引起的颅内出血。对比海绵状血管瘤的脑血管造影和 CT 扫描表现,我们发现了一个新的、对海绵状血管瘤进行定性诊断的重要征象——“矛盾现象”,这一征象是基于海绵状血管瘤病理结构本身和两种检查方法机制的不同。
This article analyzes the results of cerebrovascular angiography and CT scans of two cerebrovascular malformations (33 arteriovenous malformations and 4 cavernous hemangiomas). According to arteriovenous malformations in cerebral angiography and CT scan performance, it is divided into five types, occult, isolated, dendritic, varicose veins and aneurysm type. This article discusses intracranial hemorrhage caused by arteriovenous malformations. In contrast to cerebral angiography and CT scans of cavernous hemangiomas, we found a new and important sign of caustic hemangiomas being diagnosed qualitatively as a “paradox” based on the cavernous hemangiomas Itself and two different inspection methods and mechanisms.
