Crohn Disease – Barium Follow Through

Crohn disease. This is a magnified image from the right iliac fossa performed as part of a small bowel follow through. It shows the classic appearance of Crohn disease in the terminal ileum – so-called ‘cobblestoning’. This is caused by extensive fissures and ulceration in between areas of intact but oedematous mucosa, resembling cobblestones (arrows).
