Primary tuberculous pyomyositis in an immunocompetent individual

Tuberculous pyomyositis is a rare complication of Mycobacterium tuberculosis infection. The reported incidence is around 1% of musculoskeletal tuberculosis. In most cases, tuberculous pyomyositis is misdiagnosed as malignancy or autoimmune disorder due to its nonspecific presentation. The incidence of extrapulmonary tuberculosis is more common in patients with diabetes mellitus and immunocompromised individuals. The reported incidence of mortality in tuberculous pyomyositis is more than 30%. We report a patient of primary tuberculous pyomyositis of the back extending up to right hypochondrium. He was diagnosed with histopathological examination and microbiological examination of aspirate from the muscle. Prompt diagnosis and treatment can save the patient’s life in tuberculous pyomyositis.
