Tuberculous pyomyositis in a renal transplant recipient

Infections are a major cause of morbidity and mortality in renal transplant recipients. Although these patients are susceptible to many types of infection, soft tissue infections are rare. We report a case of tuberculous pyomyositis involving the left erector spinae muscle but with no other manifestations of tuberculosis. The diagnosis was suspected from the CT scan appearance and confirmed by microscopy and culture of the pus. Surgical incision and drainage, together with antituberculosis therapy, cured the infection. The relevant literature is briefly reviewed.
