title: Interictal regional delta slowing in cerebral sinus vein thrombosis.
abstract: The electroencephalographic finding of regional delta activity should alert to the possibility of an underlying structural abnormality of the brain as a cause. A 5-year-old boy, who presented with severe headache and focal seizures, had normal neurological examination and brain CT findings. The initial electroencephalograph showed focal delta activity. An emergent brain MRI disclosed a thrombosis of the left sigmoid sinus and jugular vein, but no parenchymal lesions. The regional delta activity can presumably serve as a marker for brain tissue damage in cerebral sinus vein thrombosis, and sometimes, even to add information to that gained from imaging studies.
