Reason: 5yo F with new onset seizures, possible left basal ganglia hypoattenuation on OSH head CT History: New onset seizure, possible left basal ganglia hypoattenuation on OSH head CT There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is a solitary punctate focus in the left subinsular white matter which is hyperintense on T2 and FLAIR and hypointense on T1. This is notably not in the basal ganglia, which appear normal. 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. The paranasal sinuses are unremarkable.
1.No basal ganglia lesion or other finding to account for patient's seizures.2.Solitary punctate foci of increased T2 signal in the left subinsular white matter appears chronic and is nonspecific but may reflect a remote insult.
