Rare cause of cerebral venous sinus thrombosis: Spontaneous intracranial hypotension syndrome: A case report

Figure 1 Head computed tomography with nodular, linear hyperdense shadow in the right parietal cerebral cortex and superior sagittal sinus (white arrow).

Figure 2 Head magnetic resonance imaging with magnetic resonance venography. A: A right superior sagittal sinus strip of low signal was seen on T1-weighted imaging; B: The right superior sagittal sinus strip of low signal was seen on T2-weighted imaging; C: T1-enhanced scan shows a low signal in the right superior sagittal sinus; D: The lesion is not clearly displayed on contrast-enhanced magnetic resonance venography.

Figure 3 Head and neck computed tomographic venography. A hypointense filling defect was seen in the parasagittal sinus cortical vein of the right parietal lobe, and venous thrombosis was considered (white arrow).

Figure 4 Review of head magnetic resonance imaging. A: No abnormal signal shadow was seen in the right sagittal sinus on T1-weighted imaging; B: No abnormal signal shadow was seen in the right sagittal sinus on T2-weighted imaging; C: No abnormal signal shadow was seen in the right sagittal sinus on T1-enhanced scan.
