Cerebral venous sinus thrombosis (CVST) is an uncommon and potentially life neurological emergency. The annual incidence is estimated at 2 occlusion with a clot into a venous sinus causes an acute increase of the intracranial pressure rising to intracranial hypertension. Due to the rupture of cortical veins both parenchymal brain hemorrhage and subarachnoidal hemorrhage can be present in the challenge. High clinical suspicious is mandatory for an early diagnostic. Nowadays, with the use of CT and CTV its diagnosis is less difficult. Most of the patients recover without any neurological rapid initiation of anticoagulant treatment is mandatory in order to reopen the occluded venous sinus. Neither the parenchymal brain hemorrhage nor the subarachnoidal hemorrhage contraindicated the anticoagulation. The main demographics, risk factors, clinical findings, neuroradiological characteristics, treatment and outcome of 10 consecutive patients with the diagnosis of CVST in a single public medical center in Costa Rica are described
