A 78-year-old female patient visited her doctor complaining of lower abdominal pain. She was diagnosed as having ischemic colitis and treated conservatively. However, the symptom failed to improve and she was referred to our hospital for further examination and treatment. Abdominal computed tomography revealed fluid retention in the left adnexa and a fistula formation with the sigmoid diverticulum. We made the diagnosis of tubal abscess secondary to sigmoid diverticulitis and performed sigmoid colectomy, total hysterectomy, and bilateral salpingo-oophorectomy. The patient was discharged on the 16th postoperative day without any complications. Adnexal perforation caused by sigmoid diverticulitis is rare. Conservative treatment alone often fails, so that surgical treatment is considered.
