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.

Primary Cutaneous Aspergillosis Presenting as a Multiloculated Cyst in the Hand

“…The wall of this lesion was thin and smooth, which was not correlated with previous report. However, central T2 hyperintensity of the lesion might be helpful in ruling out tuberculous infection because central caseous necrosis of tuberculous infection is mostly seen as isointensity or hypointensity on T1 and T2 weighted images (14,15). The wall of the cystic lesion showed low signal intensity on T2 weighted images and intermediate to high signal intensity on T1 weighted images.…”
