Caecum has gone from normal right iliac fossa position (previous scan) to enter the space between liver and hemidiaphragm (current scan), taking the ileo-colic artery with it. Distended caecum and small bowel (obstruction) with adjacent free fluid, indicating the possibility of venous ischaemia in the volved segment. Note how the liver has become grossly distorted by the markedly distended caecum.
