Known multiple sclerosis with recent numbness of right arm and leg: decreased vibration and joint sense on the right. There are multiple T2 hyperintense cerebral white matter lesions. There appears to be a new subcentimeter lesion in the left inferior frontal gyrus deep white matter since 2011. However, a left temporal stem lesion appears to be smaller. The other lesions appears to be unchanged. There is no abnormal intracranial enhancement. 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 mastoid air cells are grossly unremarkable. There are several scalp nodules, which have increased in size since 2011 and likely represent inclusion or pilar cysts. The largest of these is in the right frontal scalp, which measures up to 20 mm.
