Appendicitis with localized perforation and abscess formation

Case contributed by Dr Matthew Lukies


Four day history of right lower quadrant abdominal pain and minimal bowel movements.

Patient Data

Age: 85
Gender: Male

Main findings:

  • thick walled blind-ending vermiform structure arising from the cecum inferior to the ileocecal valve, measuring up to 13 mm in diameter
  • fat stranding around the vermiform structure and an adjacent rounded fluid density without gas locules

These findings are consistent with appendicitis with localized perforation and collection.

Other incidental findings on this CT are:

  • surgical clips in the right inguinal canal consistent with past history of hernia repair
  • uncomplicated sigmoid colonic diverticulae
  • small focal pouch aneurysm of the abdominal aorta just distal to the IMA origin
  • bilateral L5 pars defects and grade 1 L5, S1 anterolisthesis (longstanding)
  • right renal cortical cyst

Case Discussion

The patient in this case proceeded to laparoscopic surgery where an abscess was drained and the appendix removed. Histopathology confirmed the diagnosis of appendicitis.
