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