Venous aneurysms so-called isolated cerebral varix, are known as a related pathology in arteriovenous malformations (AVM) due to the arterial pressure on venous drainage (16). They are also observed in combination with developmental venous anomalies (DVA) (2,4,8,15). However, isolated varix is a rare entity (1,7,11,13). They appear in most cases without neurological deficits. Some of the cases mimic a meningioma due to their manifestation in CT and MR imaging and their axial cortical localization. The case presented here is a isolated varix of a cortical vein located rostral to the motor strip. The patient was operated on successfully. The MRI and the histology of the case are presented.
静脉瘤即所谓的孤立性脑静脉扩张，因动脉对静脉引流的压力，被认为是动静脉畸形（AVM）的相关病理表现（16）。它们也可与发育性静脉异常（DVA）同时出现（2,4,8,15）。然而，孤立性静脉扩张是一种罕见的病症（1,7,11,13）。大多数情况下，它们出现时并无神经功能缺损。部分病例因其在CT和磁共振成像中的表现以及轴位皮质定位，类似脑膜瘤。此处呈现的病例是位于运动区前方的皮质静脉孤立性静脉扩张。该患者手术成功。文中展示了该病例的磁共振成像及组织学情况。
