Bottom Line: 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.Abstract available from the publisher.

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.

Tuberculous lymph node disease in a 55-year-old, male patient. Multiple enlargedlymph nodes (arrows) with central necrosis in periaortic, pericaval andinteraortocaval chains. Large tuberculous abscesses in both psoas muscles (P) andsmall amount of ascites (asterisk) are observed.

Mentions: The lymph node disease pattern is variable at CT, most frequently demonstrating lymphnode enlargement (40-60%) with hypoattenuation in the center and hyperattenuation in theperiphery, after intravenous contrast injection, which is typical but not pathognomonicof caseous necrosis (Figure 3)(9). Lymphoma, metastasis, pyogenicinfection and Whipple's disease are the main differential diagnoses(11,16). Other lymph node involvement patterns include increase in thenumber but not in volume of lymph nodes, large, localized lymph nodes clusters andconglomerates (Figure 4)(16).
