Case contributed by Dr Sachin Pathak

Presentation

Severe headache, giddiness. On examination the patient had bradycardia and mild pappioedema.

the superior sagittal sinus appear hyperdense on noncontrast CT images.
 

Note loss of flow void in the superior sagittal sinus on T2WI. 

Abnormal hyperinese cortical /subcortical areas on FLAIR images in bilateral high fronal &  parietal lobes.

GRE images reveal the 'cord' sign with blooming of the thrombosed SSS & cortical veins.

MRV confirms the findings of extensive dural venous sinus thrombosis

Case Discussion

The superior sagittal sinus & a superficial right parietal cotical vein appear hyperdense on noncontrast CT images. Note loss of flow void in the superior sagittal sinus on T2WI. Abnormal hyperintense cortical and subcortical areas on FLAIR images in bilateral high fronal & parietal lobes are also present.

Features are consistent with a dural venous sinus thrombosis.
