A non-contrast CT head showed a large left frontoparietal subdural hematoma with fluid level and significant mid line shift (Fig. 1A). CT scan and MRI (Fig. 1B). CT head obtained 3 months earlier did not show any form of intracranial hemorrhage. The superior sagittal sinus appeared hypoplastic (Fig. 1D-F). In the venous phase a prominent left vein of Labbe was noted draining almost the entire left cerebral hemisphere (Fig. 1E). Also there were multiple venous angiomas in the cerebral hemisphere and the cerebellum (Fig. 1F). Bilateral perisylvian polymicrogyria was observed on MRI brain (Fig. 1C).
