CT is also useful for evaluating the complications of acute cholecystitis, such as emphysematous cholecystitis, gangrenous cholecystitis, haemorrhage, and gallstone ileus. CT plays a critical role in patient management by suggesting the correct diagnosis based on characteristic imaging findings, identifying the complications especially in critically ill patients and reduce the morbidity and mortality by immediate percutaneous cholecystostomy or cholecystectomy.

A large number of incidental gastrointestinal findings can be observed during abdominal MDCT exam; they can be divided into benign, indeterminate, and worrisome [1]; even if the most frequent are benign ones, there are several conditions such as abdominal hernias, giant colon diverticulum, GIST, intestinal pneumatosis, colon ischemia, cold intussusception, gallstone ileus, and foreign bodies that represent a clinical medical emergency, and because of that a strait clinical and surgical attention may be needed (Table 1).
Bezoar-induced obstruction should be distinguished from gallstone ileus because bezoars produce the same sonographic image as ectopic lithiasis.
