Hypertrophic ileocaecal valve simulating a malignant tumour. A case report.

A patient presented with rectal bleeding which, on investigation, was though to be due to a polyp within the caecum. The benign nature of the lesion could not be established conclusively without surgical exploration. A limited right hemicolectomy was performed and examination of the specimen revealed a prominent ileocaecal valve. The problem of diagnosing this entity pre-operatively is discussed.
