An Isolated Lump in Right Groin: an Unusual Initial Presentation of Crohn’s Disease

Abstract

Background: Retroperitoneal abscess, extending to the groin as an isolated tender lump, is rare as the first manifestation of Crohn’s disease.

Case presentation: This report describes a young, fit and healthy 22 year-old woman with no previous history of gastrointestinal disorder, who presented with an isolated, tender lump in her right groin as the initial presentation of Crohn’s disease. The patient, after a conventional incision and drainage of the abscess, was readmitted with enterocutaneous fistula at the right groin. After radiological investigations, she underwent a laparotomy, which showed jejunal perforation through ileocaecal mesentery producing retrocaecal abscess. There was also a suspicious fistulous connection between jejunum and ileo-caecal junction. A segmental small bowel resection and a limited right hemicolectomy with primary anastomoses were performed.

The patient made an uneventful post-operative recovery and was discharged home on the fifth post operative day. Conclusion: Crohn’s disease could manifest as an isolated, tender groin lump which has not been described in the published literature so far. Since retroperitoneal abscess remains a rare but serious complication of Crohn’s disease, aggressive operative therapy should be ensued without delay in order to remove the source of the abscess. Groin abscess could conceal surprises and should always be investigated radiologically before proceeding to incision and drainage.
