Male, 60 years old, with HIV, hypertension, end-stage renal disease, presents with seizures. Image quality is significantly limited by motion artifact. No restricted diffusion is seen. No areas of significant parenchymal edema or mass effect are observed. Asymmetric susceptibility effect is evident in the right basal ganglia which may reflect hemosiderin staining or mineralization. In addition, there appears to be some volume loss of the right basal ganglia. T2 hyperintense foci in the left basal ganglia could represent either lacunar infarcts or prominent perivascular spaces. Periventricular T2 hyperintensity is seen. No large abnormal fluid collections are detected. Allowing for mild ex vacuo dilatation of the right frontal horn, the ventricular system is unremarkable.
1.Significantly limited examination due to motion artifact.2.No definite evidence of any acute intracranial abnormality.3.Hemosiderin staining and volume loss of the right basal ganglia may represent prior ischemia.4.Findings are noted compatible with chronic microvascular ischemic disease.
