1. Cerebral venous sinus thrombosis.
Cerebral venous sinus thrombosis. A and B, Precontrast T1-weighted (A) and T2-weighted (B) images show normal cerebral parenchyma except in the sagittal sinus (arrow), where a hyperintense (T1) and isointense (T2) thrombus is replacing the normal low signal intensity of flowing blood. C, SWI shows significant engorgement of the venous system of the whole brain because of venous hypertension secondary to CVST. D, Three months later (after thrombolytic therapy), SWI shows a return to a normal-appearing venous system. Courtesy of Dr Guangbin Wang, Shandong Medical Imaging Research Institute, Jinan, China.
