RESUMEN
We present a case of a 30-year-old Hispanic male with pelvic outlet obstruction syndrome secondary to a large pelvic abscess caused by Salmonella enterica Bovismorbificans. This case demonstrates a potentially serious complication of a rare foodborne illness in the United States, in which an urgent surgical intervention was warranted. A computed tomography (CT) scan of the abdomen and pelvis demonstrated a large pelvic cystic mass causing near-total pelvic outlet obstruction of both gastrointestinal and genitourinary systems. A total of 1,250 mg of IV vancomycin and 3.375 mg of IV piperacillin-tazobactam were administered every eight hours, and an urgent decompressive transverse loop colostomy, Foley catheter placement, and percutaneous drainage were performed. Culture of the abscess fluid identified Salmonella enterica serotype Bovismorbificans, and the antibiotic regimen was changed to 1,000 mg IV ceftriaxone every 24 hours. Subsequent CT imaging displayed a reduction in abscess size. The patient was then discharged with a 14-day course of 500 mg of oral ciprofloxacin every 12 hours and 500 mg of oral metronidazole every eight hours. Imaging at three weeks post-discharge displayed resolution of the abscess, and the drain was removed. The patient had complete recovery and did well several months following treatment. While rare, Salmonella enterica serotype Bovismorbificans could potentially lead to serious complications such as giant pelvic abscess, in which a multidisciplinary team approach (i.e., medical, surgical, and interventional) is critical for a good outcome.
