Venous Sinus Thrombosis and Venous Infarction 113 Brain Tumors

Venous Sinus Infarct

Fig. 11.11 This T1-weighted coronary MRI sequence after contrast administration shows signal loss in the right paramedian region of the cortex next to the interhemispheric fissure caused by venous infarction. A typical filling defect seen in the superior sagittal sinus is the underlying occlusive venous thrombus (arrow).

The first 6 hours are crucial in the management of stroke: The patient must be rushed into a hospital with a stroke center. Get a CT immediately to exclude hemorrhage. Unless contraindicated, initiate systemic or regional thrombolysis as soon as possible if the risks appear acceptable under the circumstances.
