Coronal CT image of the abdomen and pelvis without contrast. There is around 1 cm appendicolith seen at the appendices orifice with consequent dilatation of the residual appendix. The diameter of the residual appendix measures about 1.1 X 2 cm. The residual appendix is surrounded by significant fat stranding and multiple reactive regional lymph nodes. There is minimal pelvic free fluid. However, no free air is seen.
