RESUMEN
The goal of this teaching case study is to demonstrate the novel use of (99m)Tc-HMPAO-labeled white blood cells (WBCs) in diagnosing chronic recurrent multifocal osteomyelitis (CRMO). (99m)Tc-HMPAO-labeled white blood cells were utilized to diagnose CRMO. Classically, CRMO is evaluated scintigraphically using (99m)Tc-methylene diphosphonate/hydroxymethylene diphosphonate. (99m)Tc-HMPAO-labeled WBCs were chosen over (111)In-labeled WBCs because of the former's improved imaging characteristics and decreased radiation dose. (99m)Tc-HMPAO-labeled WBCs were successful in diagnosing CRMO. (99m)Tc-HMPAO-labeled WBC scanning is specific for the diagnosis of CRMO.

Mycobacterium kansasii is a common cause of pulmonary infection as a result of nontuberculous mycobacteria, but is less commonly described as a cause of an orthopedic infection. We present the first case of M. kansasii subacromial septic bursitis in an immunocompromised host. This case demonstrates the diagnostic and treatment challenges associated with orthopedic infections caused by M. kansasii.
