[Tuberculous pseudotumor of the omentum]

The abdomen is one of the most common extrathoracic manifestation sites for tuberculosis. The constellation of ascites, fatigue, fever, weight loss and ileus in younger patients should lead to the diagnosis, particularly in times when immunosuppression appears more frequently associated with AIDS. Using modern imaging techniques like CT and ultrasound and in combination with interventional procedures (guided paracentesis or biopsy) the number of diagnostic laparotomies and laparoscopies, like in the case presented could be reduced. In this context the radiologist should include tuberculosis in the differential diagnosis.
