12-year-old female presents with seizure relapse, leg stiffening, and uncontrollable laughing. There is a punctate focus of high T2 signal in the left anterior frontal lobe subcortical white matter. Otherwise, there is no evidence of hamartoma, gross cortical dysplasia, medial temporal lobe sclerosis, intracranial hemorrhage, mass, or 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 orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
A punctate focus of high T2 signal in the left anterior frontal lobe subcortical white matter is nonspecific, but could potentially represent heterotopic grey matter or prominent perivascular space perhaps.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
