Figure 8. Perforated appendicitis. An 18-year-old female with right lower quadrant pain, fever and leucocytosis. CT demonstrates an enlarged right ovary (large arrow) with small cystic areas in it, adjacent fluid (small arrow) and extrinsic inflammation of the adjacent mesenteric fat (arrowhead). A CT diagnosis of tubo-ovarian abscess or pelvic inflammatory disease was entertained. However, the surgical diagnosis was perforated appendicitis, abscess formation and secondary oedema of the right ovary.
