A Case of Tuberculous Psoas Abscess Caused by Tuberculous Lymphadenopathy

Abstract

A tuberculous psoas abscess is a frequently described complication of tuberculous spondylitis. Although rare, a tuberculous psoas abscess can develop without any demonstrable spinal involvement. In patients with no evidence of sponylitis, the abscess may result from direct spread from the involved lymph node or via a hematogeous route. The treatment of a psoas abscess is either drug therapy or surgical intervention in conjunction with drug therapy. Image-guided percutaneous drainage in conjunction with drug therapy is also a safe and effective treatment for a tuberculous psoas abscess. We report an unusual case of bilateral tuberculous psoas abscesses without any concomitant spinal involvement. The tuberculous psoas abscess may have formed by fistulization between the necrotic lymph node and psoas sheath. The diagnosis was confirmed by computed tomography and a histology examination of the biopsy sample. The patient improved after administering anti-tuberculous agents for 2 years along with surgical and percutaneous drainage of the abscess. (Tuberc Respir Dis 2008;65:517-521)
