Abstract

AbstractDiagnosis of abdominal tuberculosis is challenging due to its variable imaging appearance, which can mimic several other conditions. This review covers the imaging spectrum of tubercular involvement of abdominal lymph nodes, peritoneum, solid abdominal viscera, and the gastrointestinal tract. Tubercular lymphadenitis is the most frequent manifestation of abdominal tuberculosis and may show necrosis. Peritoneal tuberculosis is the next most commonly involved site in the abdomen and can be of wet, fibrotic, and dry forms. The ileocecal region is the most common site of involvement in gastrointestinal tuberculosis. Solid visceral involvement mostly affects the liver and spleen causing hepatosplenomegaly with a micronodular or macronodular imaging pattern. Awareness of the spectrum of imaging manifestations and a high index of suspicion is required to reach the correct diagnosis.
