Musculoskeletal Tuberculosis Presenting as Isolated Tuberculous Gumma in an Immunocompetent Patient

Abstract

A 57-year-old woman with no significant past medical history and normal immunity presented with a slowly growing mass on her finger. MR imaging showed a low signal intensity soft tissue mass on both T1- and T2- weighted images with peripheral contrast enhancement. The mass was diagnosed as chronic granulomatous inflammation with caseous necrosis histopathologically and also Mycobacterium tuberculosis by a polymerase chain reaction about the tissue specimen. Authors thought that it was tuberculous gumma presented in an immunocompetent patient. This paper reports a rare case of tuberculous gumma with radiologic findings in an immunocompetent patient.
