Dementia Due to HIV Infection (cont.)

Media file 1: CT scan of the brain of a patient with AIDS dementia complex (ADC) shows diffuse atrophy (loss of tissue) and ventricular enlargement and attenuation (dark areas) around the ventricles in the white matter.

Media type:  CT

Media file 2: T2-weighted MRI shows ventricular enlargement and large areas of hyperintense signal in the subcortical white matter of both frontal lobes.

Media type:  MRI

Media file 3: Photomicrograph from a patient with AIDS dementia complex (ADC) shows perivascular and parenchymal infiltrates of lymphocytes and macrophages. These often form microglial nodules. Contributed by Dr. Beth Levy, Saint Louis University School of Medicine, St. Louis, Mo.
