Tubo-ovarian abscess: A potential mimicker of urachal malignancy

Research output: Contribution to journalArticlepeer-review


Urachal cancer is a rare but aggressive malignancy. A urachal mass concerning for adenocarcinoma was identified in a 32-year-old G2P1 female on 12-week ultrasound and confirmed on pelvic MRI. Due to progressive growth of the mass and refractory abdominal pain, a multi-disciplinary meeting was held, after which the patient chose to undergo an exploratory laparotomy. A tubo-ovarian abscess was identified involving the intestine, right ovary, fallopian tube, and communicating with a patent, necrotic urachus. This is the first reported case of a tubo-ovarian abscess masquerading as a urachal malignancy, which can present similarly with abdominal pain and irritative urinary symptoms.
