Venous Sinus Thrombosis

Venous Thrombosis can arise from many different causes. Recognizing the subtle signs of this condition is crucial to proper diagnosis. This case starts with a routine non-contrast head CT that demonstrates hyper attenuation of the sagittal, transverse and straight sinuses. Within the abnormally bright sinuses, the filling defect was identified and prompted additional imaging with a MRI / MRV Brain study. Suspicion for venous thrombosis should be high when increased attenuation of the venous system is recognized. The most common locations for venous sinus thrombosis is superior sagittal sinus and transverse sinus.
