LOC and fall with head trauma; never had subsequent imaging; hx of bladder cancer. There is a subcentimeter area of high T1 and T2 signal in the right globus pallidus without restricted diffusion. There is a background of mild scattered cerebral and pontine white matter T2 hyperintensity in addition to prominent perivascular spaces. There is no evidence of mass or acute infarct. There is no abnormal intracranial enhancement. There is mild diffuse cerebral volume loss. 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.
1. A subcentimeter area of high T1 and T2 signal in the right globus pallidus may represent a subacute lacunar infarct. Otherwise, a background of mild scattered cerebral and pontine white matter T2 hyperintensity may represent chronic small vessel ischemic disease.2. No evidence of intracranial metastases.
