Cerebral venous sinus thrombosis can clinically manifest as headache, focal neurological deficit or even coma. Non-contrast CT head can show hyperdense venous sinuses (A & B, asterisks), venous infarction (A, arrow), intraparenchymal hemorrhages (B, curved arrow) or sub-arachnoid hemorrhage. Distribution of the lesions in drainage territories of particular veins or venous sinuses can be clue to the diagnosis (Note: Vein of left Labbe/transverse sinus territory venous infarction in A, arrow). Figure C shows usual drainage territories of various cerebral venous sinuses (Superior sagittal sinus- red, Cavernous sinus-green, Transverse sinus- yellow, Galenic system and straight sinus- blue). Usual treatment is anti-coagulation, however, endovascular treatment can be used in selected group of patients.
