Psoas Abscess as the presenting feature of Crohn’s Disease – a case report

Background: A case of psoas abscess as the presenting feature of Crohn’s disease is presented.
Case Report: A 21-year-old man with no previous history was admitted with signs and symptoms of an intra-abdominal abscess. Magnetic resonance imaging proved the presence of an abscess, which was drained with assistance of computed tomography. The patient deteriorated, and further imagery confirmed a bowel perforation. Laparotomy findings demonstrated psoas muscle abscess and ileo-caecal perforation in a bowel with histological evidence of Crohn’s colitis. The patient made a slow recovery.
Conclusions: Psoas abscess is a complication of Crohn’s disease but is very rarely the presenting feature. There can be delays in diagnosis and significant morbidity. Patients may require a wideranging approach to management.
