Adenocystitis with concomitant Crohn's disease leading to an outbreak of Crohn's disease with ulcerated external iliac vessels

We report a case of a young 36-year-old female patient who presented to our hospital with a diagnosis of adenocystitis presenting as a vesicovaginal fistula after cystoscopic biopsy at a local hospital because of ineffective anti-inflammatory urinary frequency and urgency and pain. The patient underwent laparoscopic vesicovaginal fistula repair after cystoscopy confirmed a vesicovaginal fistula and postoperatively developed a Crohn's disease outbreak with multiple small bowel fistulas and erosion of the external iliac vessels that ruptured to form an external iliac vessel small bowel fistula. The case was confirmed by surgical exploration, and the patient eventually died.
