Seizure activity. There is extensive volume loss related to cystic encephalomalacia predominantly involving the left parietal lobe. There are adjacent areas of gyriform high T1 signal as well as high T1 signal in the left basal ganglia. There is ex vacuo dilatation of the left lateral ventricle. There is no evidence of acute intracranial hemorrhage, mass, or acute infarct. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits are grossly unremarkable. There are areas of nodular low T1 signal in the midline and right occipital scalp.
1. Findings compatible with chronic left middle cerebral artery territory infarction predominantly involving the left basal ganglia and parietal lobe. 2. Incompletely characterized areas of nodular low T1 signal in the occipital scalp are nonspecific.
