Tuboovarian abscess as unusual presentation of tubarian fistula secondary to sigmoid diverticulitis.

A 80-year-old female with hypertension and aortic valve disease, as a past medical history, who went to the emergency department with abdominal pain located in right lower quadrant and leukocytosis. The sonographic exploration identified a formation adjacent to the uterus of 44 x 36 mm, heterogeneous, probably related to a right adnexal mass, so she was admitted onto the gynecology service. A multidetector computed tomography (TCM) revealed a collection with air inside, adjacent to the uterus, and a distended and enhancement of the right tube`s walls. It caused endometrial retention and there was an air bubble in the uterine cavity. These findings correspond to salpingitis and tuboovarian abscess. There was a segment of the adjacent sigma with walls slightly thickened and diverticula. The patient was diagnosed with perforated diverticulitis with an abscess in the broad ligament. The collection underwent drainage and intravenous antibiotics were prescribed with clinical and radiology improvement.
