An atypical clinical presentation of acute appendicitis in a young man with midgut malrotation

An unusual presentation of acute appendicitis, with fever and recurrent pain in left iliac fossa is reported. Underlying intestinal malrotation delayed the correct clinical diagnosis of acute appendicitis. It was not until a CT scan was performed that a malrotation was identified. The predominant appearances of malrotation are the siting of the ascending colon, caecum (and appendix) in the left side of the abdomen and the right-sided placement of the duodenojejunal junction.
