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.

No MeSH data available.

Mentions: The macronodular presentation (Figure 8) is rarer,less frequently associated with the pulmonary form of tuberculosis and it is related todissemination through the portal vein(4,21). Calcifications mayarise in the chronic phase of the disease(7,9,16). At CT, lesions measuring between 1 and 3 cm in diameter orsingle mass may be observed in a diffusely enlarged liver. At MRI, the lesions presentlow signal intensity and minimal peripheral enhancement, with a honeycombing pattern inthe miliary form at T1-weighted sequences (Figure7). At T2-weighted sequences, the lesions are hypointense, with a lesshypointense halo in relation to the surrounding liver parenchyma(12).
