Colouterine Fistula Masquerading as a Complex Adnexal Mass: A Case Report

Area of Science:

• Gastroenterology
• Gynecologic Surgery

Background:

• Colouterine fistula is an exceptionally rare complication of diverticulitis, with limited reported cases.
• No standardized diagnostic methods exist due to its infrequent occurrence.

Observation:

• A 66-year-old woman with a history of diverticulitis presented with vaginal bleeding and discharge.
• Initial imaging suggested a complex adnexal mass, but intraoperative findings confirmed a colouterine fistula.

Findings:

• Diagnosis of colouterine fistula can be achieved through pelvic examination, imaging studies, or surgical exploration.
• Surgical treatment strategies depend on the severity of diverticular disease and suspicion of malignancy.

Implications:

• Highlights the importance of considering colouterine fistula in the differential diagnosis of unexplained vaginal discharge or bleeding in patients with diverticulitis.
• Emphasizes the need for tailored surgical approaches based on individual patient factors.
