Assess for seizure focus: 2 GTCs. There is a subcentimeter focus of high T1 signal with susceptibility effect in the left posterior basal ganglia. There is mild scattered cerebral white matter T2 hyperintensity bilaterally. The hippocampi are unremarkable and there is no evidence of heterotopia. There is also no evidence of intracranial hemorrhage, mass, or acute infarct. 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 paranasal sinuses and scalp soft tissues are grossly unremarkable. There is deformity of the nasal skeleton related to prior trauma. There are bilateral lens implants.
1. Nonspecific subcentimeter focus of mineralization in the left posterior basal ganglia, but otherwise no evidence of potential seizure foci. 2. Mild scattered cerebral white matter T2 hyperintensity bilaterally is nonspecific, but may represent chronic small vessel ischemic disease.
