 There is a subcentimeter focus of high T2 signal in the midline of the splenium of the corpus callosum. The rest of the brain parenchyma appears unremarkable. 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.
A subcentimeter focus of high T2 signal in the midline of the splenium of the corpus callosum may represent a transient splenial lesion, which can be a manifestation of viral encephalitis, epilepsy, and drug reaction, for example. Otherwise, no evidence of acute intracranial hemorrhage, mass, or acute infarct. Nevertheless, a follow up brain MRI may be useful.
