46-year-old with paresthesias. Evaluate for demyelinating disease. There is a single punctate focus of increased T2 signal in the right temporal lobe subcortical white matter. The remaining brain parenchyma is unremarkable.There is no evidence of intracranial hemorrhage, mass or edema. The ventricles and basal cisterns are normal in size and configuration. The expected intracranial vascular flow voids are present. The paranasal sinuses are clear. The visualized mastoid air cells are clear. The orbits are unremarkable.
1. Single punctate focus of increased T2/FLAIR signal in the right temporal lobe. This is nonspecific given the small size and singularity of the lesion.2. No evidence of acute ischemic or hemorrhagic lesion
