VOLUMINOUS RETROPERITONEAL TUBERCULOUS ABSCESS

Tuberculosis mostly affects the lungs, but many unusual localizations has been reported [1- 3]. The course of the disease could be extremely serious if the diagnosis is missed. We're reporting here a 50-year- old man suffering from right lower back pain for 02 weeks, with loss of weight and deterioration of the general sate. The clinical exam revealed a wheelbase of the right lumbar fossa and inflammatory skin signs. The biological assessment showed moderate inflammatory syndrome. Abdominal CT was performed, showing a voluminous right retroperitoneal abscess in pre-fistulization in the skin, measuring 10.7x8.4x6.7 cm, exerting an important mass effect on the ipsi-lateral kidney (Figures A & B). Percutaneous drainage was performed first. The bacteriological analysis of the purulent fluid affirmed tubercular origin. An antituberculosis treatment was introduced with good clinical and radiological evolution. In endemic regions and in patients with HIV infection [4], diagnosis of tuberculosis abscess should not be missed out.
