Case Discussion

The patient presented with abdominal pain and vomiting. On examination, there was considerable abdominal distension and additionally raised inflammatory markers.

CT revealed small bowel distension with no definite transition point. However, there is subtle fat stranding in the right iliac fossa and an inflamed appendix.

This case highlights how patients with acute intra-abdominal infection can present with obstructive symptoms, when in fact, there is not complete obstruction and this is a case of small bowel pseudo-obstruction secondary to appendicitis.

The appendicitis was managed successfully and conservatively with antibiotics.
