Irregularly shaped hemorrhage in the right parietal lobe on the edge of white and gray mater. Parenchymal hemorrhage can be seen in one-third of cases of cerebral venous thrombosis.
Abnormal hyperattenuation consistent to direct visualization of a clot in the straight sinus on a non enhanced CT scan (Dense clot sign) (in 1/3 of cases)
Note the hyperdense presentation of SSS (Dense delta / filled triangle sign). This is not specific and can be observed occasionally in patients with an elevated hematocrit.
Contrast-enhanced CT image shows a central filling defect in the SSS, surrounded by intensely enhanced dura mater (Empty delta / empty triangle sign). It is seen in 25–52% of patients with sagittal, straight, and lateral sinus thrombosis.
