Cerebral Venous Malformation:Imaging Diagnosis and Evaluation / 实用放射学杂志

ABSTRACT

Objective To evaluate the value and limitation of CTA, MRI and DSA in the diagnosis of the cerebral venous malformation. Methods CT angiography in 8 cases and MRI in 10 cases were performed among 12 cases of cerebral venous malformation confirmed by carotid angiography . Results All cases had typical DSA appearance and it could be seen both the number and the direction of the guide vein. The typical “Medusa-head” sign could be seen on MRI and could be more obvious after contrast enhancement.The other complications might be seen on the postcontrast. On CTA,both the lesion itself and the “caput medusae”sign could be displayed.Conclusion In diagnosis of cerebral venous malformation,DSA is the gold standard,CTA is the significant method in diagnosing and following up,while MRI is the most useful method.
