Abstract

Objective: To study the characteristic features of MRI in cerebral venous sinus thrombosis. Methods and Methods: A retrospective review of 13 patients with cerebral venous sinus thrombosis was made from December 2003 to January 2005. MR examination was performed on 1.5T superconductive scanner in multiple planes. MR venography were acquired by using techniques of 2D-TOF. Results: MRI showed disappearance of the normal flow void signal of the cerebral venous sinus, abnormal high signal intensities were found instead. The superior sagittal sinus and transverse sinus were most frequently involved. MR venography demonstrated filling defect and no flow void signal, stenosis or a recanalized sinus in these involved venous sinus. Collateral circulation became prominent, flow signal from deeper vein were seen, or emissary vein were visualized. Conclusion: MRI and MRV can be used for diagnosing and follow-up study in cerebral venous sinus thrombosis.
