18F-FDG Uptake in Subcutaneous Fat Preceding Clinical Diagnosis of Human Immunodeficiency Virus–Associated LipodystrophyCaton, Michael T.

The examination showed unusual radiotracer distribution accumulating in the subcutaneous and visceral fat with low cerebral and skeletal muscle uptake. Imaging features were consistent with HIV-associated lipodystrophy, an unsuspected diagnosis that was later confirmed on physical examination. Recognition of HIV-associated lipodystrophy by the nuclear medicine physician is critical as altered biodistribution may affect diagnostic yield or be mistaken for infectious pathology.
