ABSTRACT
Tuberculosis is a disease whose incidence has increased principally as a consequence of HIV infection and use of immunosuppressive drugs. The abdomen is the most common site of extrapulmonary tuberculosis. It may be confused with several different conditions such as inflammatory bowel disease, cancer and other infectious diseases. Delay in the diagnosis may result in significantly increased morbidity, and therefore an early recognition of the condition is essential for proper treatment. In the present essay, cases with confirmed diagnosis of abdominal tuberculosis were assessed by means of computed tomography and magnetic resonance imaging, demonstrating the involvement of different organs and systems, and presentations which frequently lead radiologists to a diagnostic dilemma. A brief literature review was focused on imaging findings and their respective prevalence.

Mentions: Despite a certain difficulty in differentiating between the several abdominaltuberculosis presentations, besides a considerable superimposition of presentationpatterns, peritoneal tuberculosis is classically classified into three types accordingto its macroscopic aspects, namely: dry, wet and fibrous types(7,9,11-13). The wet type (Figure 1)presents primarily either as free or loculated ascites, associated or not with diffuseand smooth peritoneal thickening; in the dry type, there is a predominance of peritonealand mesenteric thickening with caseous nodules, lymph nodes enlargement and fibrinousadhesions; on its turn, the fibrous type (Figure2) is characterized by remarkable omental thickening and entanglement of bowelloops clinically resembling a mass, occasionally with loculated ascites and that may besimilar to peritoneal carcinomatosis(7,14).
