1. Ingested or inserted foreign bodies in children or adults can present to the emergency radiology for accurate location and to determine extent of damage induced by them. 2. Perforation occurs in < 1% of ingested foreign bodies and commonly misdiagnosed. 3. Sharp & blunt foreign bodies both can lead to perforation. 4. The perforation tends to occur in regions of acute angulation, such as ileocecal and rectosigmoid regions.

1. Ultrasound is sensitive in finding hyper-reflective foreign bodies but is of limited value in small/ sonolucent foreign bodies 2. X ray can only detect metallic FB, but can give clues such as pneumoperitoneum is seldom to be observed because they may be covered and limited by fibrin and adjacent loops. 3. Direct and indirect signs of FB perforation on CT 4. For detecting thin high-density FB and very small quantities of extraluminal gas, an unenhanced entire gut CT scan without oral contrast need be performed and its multiple planer reconstruction, especially coronal image should be evaluated scrupulously.
