Cerebral Venous Sinus Thrombosis and Venous Hemorrhagic Infarction in a Young Woman

Cerebral venous sinus thrombosis (CVST) is an uncommon cause of cerebral infarction, compared to arterial diseases. It is often unrecognized at initial presentation due to the diversity of causes and clinical manifestations. A 29-year-old female patient complained of severe headache and presented at the emergency room with altered consciousness. Brain computed tomography and brain magnetic resonance image revealed the left sigmoid sinus thrombosis with venous hemorrhagic infarction (VHI) in the left temporal lobe. The patient had no past medical and family history of bleeding diathesis. The laboratory finding at the admission showed severe iron-deficiency anemia (IDA), and protein C and S activities were decreased. After the neurosurgery, iron replacement, and neurorehabilitation, the patient had a good recovery. There has been no known recurrence. We report our therapeutic intervention on a very rare case of CVST and VHI, with IDA as a probable cause of cerebral thrombosis.
