Failure of indium-111 leukocyte scanning to detect nodal involvement with Mycobacterium avium-intracellulare infection in the acquired immunodeficiency syndrome.

An In-111 leukocyte scan was used to evaluate fever of unknown origin in a patient with the AIDS rather than Ga-67. The scan was normal despite an impressively positive Ga-67 scan performed 48 hours later. In-111 should not be used to evaluate fever in patients with AIDS where mycrobacterium avium-intracellular infection is a diagnostic possibility.
