Trombosis de senos venosos en el tercer trimestre de gestación

Cerebral venous thrombosis is an uncommon disease during pregnancy. The etiology is unknown in 25-40% of cases. Risk factors are infectious diseases, pregnancy, puerperium, dehydration, oral contraception use, hypercoagulative states, tumors, and traumatisms. We present a case of cerebral venous thrombosis and discuss the importance of performing a complete neurological examination in pregnant women presenting with abnormal neurological symptoms. With correct diagnosis and early treatment, outcome is usually favorable.
