Conclusions

The radiological evaluation of an acute abdomen is often difficult and it is essential for the radiologist to be familiar with the appearances of the normal abdomen. The assessment of any abnormalities is based on a variety of radiological observations including the detection of abnormal collections of gas or fluid inside or outside the gastrointestinal tract; the demonstration of calcification, masses, and the enlargement or displacement of organs; and the recognitition of any effacement of normal anatomical structures and contours. Any radiological interpretation should always be undertaken in the light of a detailed knowledge of the patient's history and clinical presentation.
