Reversible Parkinsonism caused by deep cerebral venous sinus thrombosis

Abstract

Cerebral venous sinus thrombosis (CVST) is an uncommon but serious disorder with highly variable clinical presentation. Over the past decade, more cases of CVST have been diagnosed more frequently and at an early stage of the disease process. This is mainly attributed to increased awareness by neurologists and the availability of sensitive non-invasive neuro-imaging techniques. Cerebral venous sinus thrombosis often affects children, adolescents, and young adults with female preponderance. We report a case of Parkinsonism secondary to deep CVST (DCVST), which recovered completely following treatment. Recognition of DCVST as a cause for Parkinsonism is of paramount importance due to its reversibility and favorable outcome when appropriately managed.
