AIDS-Related MR Hyperintensity of the Basal Ganglia
AJNR 19:83-89, Meltzer,C.C.,et al, 1998
See this aricle in Pubmed

Article Abstract
All patients presented acutely with new seizures or changes in mental status.A history of drug abuse was elicited in seven of the nine remaining patients.Renal failure was present in six cases.Symmetric bilateral caudate and putamen hyperintensity on T2-weighted images was found in all cases with variable extension to the surrounding white matter,thalamus,and brain stem.Postmortem neuropathologic examination in two cases revealed numerous microinfarcts in a distribution similar to the MR signal abnormalities.The MR appearance of basal ganglia hyperintensity in this series of AIDS patients represents ischemic tissue injury.We propose that this clinicopathologic entity is precipitated by the combined effects of human immunodeficiency virus infection and drug use,particularly cocaine and/or associated toxic contaminants.
