BACKGROUNDThe retroperitoneum contains the adrenals, kidneys and ureters, the duodenal loop, pancreas, great vessels with their branches and associated lymph node chains, ascending and descending portions of the colon including the caecum, the retroperitoneal sonographic images are frequently degraded by bowel gas, thick muscles, fat, ribs, the lower lungs.

BACKGROUNDThe anatomical location of pancreas at stomach bed makes its optimal visualisation a challenge due to bowel gases. These difficulties can be minimised by consistently and continuously optimising patient factors and machine settings and using excellent scanning techniques. Aims and Objectives -To study the various features of pancreatic lesions by ultrasonography and assess the role of ultrasound.
