Meningitis complicated by thrombosis of superior sagittal sinus

Contrast-enhanced MR imaging in transverse (A, B) and sagittal (C) planes shows filling defects (arrows) in superior sagittal sinus consistent with thrombosis. There is also leptomeningeal contrast enhancement (circle) indicating leptomeningitis. MR venography (D) confirms thrombosis of anterior and mid-superior sagittal sinus.
