History of CVA as a toddler, now with dizziness and palpations. There is paucity of white matter and mild periventricular T2 hyperintensity in the bilateral posterior cerebral hemispheres, with concomitant thinning of the posterior corpus callosum and enlargement of the posterior lateral ventricles. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, and scalp soft tissues are grossly unremarkable. There is left maxillary and ethmoid sinus mucosal thickening.
Findings compatible with bilateral posterior cerebral hemisphere periventricular leukomalacia, but no evidence of acute intracranial hemorrhage, mass, or acute infarct.
