Bilateral recurrent pyosalpinx in a sexually inactive 12-year-old girl secondary to rare variant of Mullerian duct anomaly.

Pyosalpinx is a severe sequel of chronic pelvic inflammatory disease, whereby the fallopian tubes become filled with pus. Pyosalpinx often affects sexually active women and rarely is seen in celibate adolescent girls. We report a case of a 12-year-old girl with no prior sexual history who presented to our emergency department with complaints of severe right lower quadrant pain of 1-day duration. 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.
