37-year-old male with new onset seizure. Evaluate for etiology of the seizure. There is scattered mild nonspecific periventricular and subcortical white matter T2/FLAIR signal abnormality. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma appears within normal limits. No findings to suggest seizure focus are appreciated. Specifically, there is no evidence of gray matter heterotopia or cortical dysplasia. The bilateral hippocampi are symmetric in size, signal characteristics, and with preserved internal architecture. There is no abnormal intracranial enhancement. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, and scalp soft tissues are grossly unremarkable. There is a left maxillary sinus mucous retention cyst and mild right maxillary sinus mucosal thickening.
1.No evidence of acute intracranial hemorrhage, mass or acute infarct.2.No findings to suggest seizure focus are appreciated.3.There is scattered mild periventricular and subcortical white matter T2/FLAIR signal abnormality which is nonspecific and may represent mild chronic small vessel ischemic disease (which would be slightly advanced for age), prior inflammation or less likely a demyelinating process.
