Multiple Intracranial Dural Sinus Thrombosis associated with Polycythemia: Case Report

Cerebral venous thrombosis is commonly related to infectious processes, trauma, neoplasm, puerperium, and the use of oral contraceptives, etc., but this case was associated with a very rare condition, "polycythemia". This case was confirmed by hematologic study, brain C-T, conventional angiography, and digital subtraction angiography(DSA). The patient was treated by venesection, the use of urokinase and dicumarol, and lumbo-peritoneal shunt(L-P shunt), etc. Post-treatment DSA showed the complete recanalization of all dural sinuses except the left transverse sinus, suggesting normal variant.
