5 week old male ex 40 weeker with recurrent global and focal seizures. There are subcentimeter foci of low T1 and high T2 signal in the bilateral thalami, as well as peripheral T1 hyperintensity in the right side. The degree of myelination otherwise appears to be within normal limits. There is 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 orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
Subcentimeter lesions in the bilateral thalami may represent chronic infarcts, but no evidence of acute intracranial hemorrhage, mass, or acute infarct.
