Piomiositis tuberculosa en un paciente inmunosuprimido

Tuberculous pyomyositis is a rare manifestation of extrapulmonary tuberculosis, most common in immunosuppressed patients, with clinical manifestations similar to pyomyositis of other etiologies, although with a lower age of presentation; notable risk factors include prior tuberculosis infection and pharmacological immunosuppression. Diagnosis depends on a high clinical suspicion of the infection in a susceptible population, given that microbiological isolation is often impossible. The response to treatment and prognosis are good. The case presented here is noteworthy given the rarity of this manifestation of tuberculosis and the slow response to first-line TB management in an HIV patient, despite susceptible microbiological isolation.
