Ultrasonography and CT scan of the abdomen and pelvis revealed free fluid collections in the pelvis without visualisation of the appendix. A preoperative diagnosis of acute ruptured appendicitis was given and she was taken to the operating room. Peroperative findings included bilaterally distended, pus-filled pyosalpinges. A definitive diagnosis of bilateral pyosalpinx was then made. Two-week antibiotic therapy was successful but the patient returned with recurrent pyosalpinx and a pelvic abscess 9 weeks later.
