Cortical venous aneurysm isolated cerebral varix.
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.
