AI Article Synopsis
- - The presence of delta activity in an electroencephalogram (EEG) can indicate potential brain structural issues, especially in patients with severe headaches and seizures.
- - A case involving a 5-year-old boy showed normal brain CT results but abnormal EEG findings, which led to further investigation.
- - An MRI revealed blood clots in the left sigmoid sinus and jugular vein without any brain tissue damage, suggesting that delta activity may indicate brain damage related to sinus vein thrombosis, enhancing understanding beyond imaging results.
Article 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.
