Left periventricular parietoccipital white matter lesion, re-evaluate for progression: transient left hemisensory syndrome, with persistent left retro-orbital headache. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is an unchanged T2 hyperintense periventricular parietoccipital white matter lesion that measures up to 25 mm. There is no abnormal intracranial enhancement. There is asymmetry of the lateral ventricles, right larger than left. There is no midline shift or herniation. The major cerebral flow voids are intact. There is mild plagiocephaly. The orbits, paranasal sinuses, and scalp soft tissues are grossly unremarkable. There is left greater than right tympanomastoid fluid.
A periventricular parietoccipital white matter lesion may represent the sequela of remote ischemic injury. No evidence of intracranial hemorrhage, mass, or acute infarct.
