Emergency Body CT > Inflammation > Appendicitis


Acute appendicitis remains one of the most common causes of abdominal pain. Right lower quadrant pain, fever and leukocytosis are the classical clinical findings. CT and US are being used more often to confirm clinical suspicions and reduce the number of unnecessary laporotomies.

General CT findings for acute appendicitis include:
1. Dilated appendix greater than 6 mm or visualization of an appendicolith with an appendix of any size
2. Peri-appendicial fat stranding

This image of an acute abdomen (arrow) displays
periappendicial stranding and dilattion of its
terminal portion.

For comparison, this image of a normal appendix (arrow)
can be visualized at the ileocecal junction. Also note
the fat-containing ventral heria (arrowhead).
