Imaging of abdominal tuberculosis.

The concept of "abdominal tuberculosis" in this review refers to peritoneum and its reflections, gastrointestinal tract, abdominal lymphatic system, and solid visceral organs, as they are subject to varying degrees of involvement alone or in combination. Some features, including free or loculated ascites with thin-mobile septa, smooth peritoneal thickening and enhancement, misty mesentery with large lymph nodes, smudged omental involvement, and advanced ileocecal changes demonstrated by US, CT, or gastrointestinal series are deemed suggestive radiological findings. The diagnosis still requires a high index of suspicion, once the suggestive features have been demonstrated by imaging modalities.
