Tubo-ovarian abscess presenting as pneumoperitoneum.

BACKGROUND

Tubo-ovarian abscess (TOA), a serious complication of pelvic inflammatory disease, often require the antibiotic administration, surgical resection or the transvaginal aspiration. Pneumoperitoneum is often associated with the bowel perforation. We reported one case with TOA and pneumoperitoneum that have been mistaken for a perforated bowel with concomitant adnexal mass.

METHODS

A 30-year-old diabetic Chinese woman was transferred for diffused abdominal pain, mild fever, nausea, and low-grade fever for 5 days. The sonography revealed a 5-cm adnexal mass. The chest X-rays revealed the pneumoperitoneum. Under the impression of bowel perforation and concomitant adnexal cyst, the emergent laparotomy was performed and the TOA was resected. No evidence of gastrointestinal perforation was present. Culture studies showed Escherichia coli without other bacteria flora. The postoperative course was uneventful.

CONCLUSIONS

We concluded that, beside the bowel perforation, TOA should be considered when a diabetic woman presents with pneumoperitoneum and adnexal mass.
