Case Report

A case of cerebral venous sinus thrombosis mimicking transient ischemic attack

A 48-year-old woman with a right-sided headache beginning a month prior to admission presented with suddenonset right hemiparesis. On admission, she had weakness of the right lower extremity, which disappeared 3 hours after onset. Contrast enhanced brain MRI revealed no parenchymal lesion, while indicated thrombi in the superior sagittal sinus and the right side of the transverse sinus, sigmoid sinus, and internal jugular vein, leading to the diagnosis of cerebral venous sinus thrombosis. Brain perfusion single photon emission computed tomography presented slightly decreased blood flow in the bilateral frontal lobes (left-sided dominant) and the right occipitotemporal lobe. Electroencephalogram showed no abnormal finding. After anticoagulant therapy, thrombi in the venous sinuses decreased and brain blood flow improved. We should consider cerebral venous sinus thrombosis in the case of a patient presenting with symptoms of a transient ischemic attack accompanied with headache. Moreover, the etiology of transient neurological deficits remains controversial.
