Abstract

Nocardiosis is uncommon. Immunocompromising conditions predispose individuals to pulmonary and disseminated nocardiosis of the brain, skin, and subcutaneous tissues. The most common pathogens are Nocardia cyriacigeorgica, Nocardia nova, and Nocardia farcinica. The speciation of Nocardia to determine antimicrobial susceptibility is difficult using traditional biochemical methods. Here, we report the case of a 73-year-old man with chronic obstructive lung disease who developed a rapidly progressing intramuscular abscess around the left hip and thigh. Within 3 days, the lesions progressed to an epidural abscess at the L4 to S1 level. Although he was treated with broad-spectrum antibiotics and extensive incision and drainage, he died of rapidly progressive respiratory failure. Nocardia abscessus (N. abscessus) was identified in pus samples using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). This case shows that the diagnosis of an intramuscular abscess caused by N. abscessus is challenging and that using MALDI-TOF MS may facilitate the diagnosis and ensure appropriate treatment.
