Cerebral venous thrombosis is an uncommon problem with serious medical consequences. It presents with a wide range of signs and symptoms as any cerebral syndrome where neuroimaging plays a key role. Among the conditions that produce or predispose to venous thrombosis are hypercoagulable states, inherited or acquired. We report a case where the association of pregnancy and malignancy (Non-Hodgkin Lymphoma) induced the development of cerebral venous sinus thrombosis.
