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 drainage16. They are also observed in combination with developmental venous anomalies (DVA)2,4,8,15. However, isolated varix is a rare entity1,7,11,13. 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.
