The magnetic resonance (MR) enterography technique has improved over the past few years to provide an excellent means of evaluating the gastrointestinal tract for suspected Crohn's disease. Although the prevalent intestinal manifestations of Crohn's disease have been extensively discussed in the radiology literature, some of its rare complications, especially extra intestinal, have received less attention. Uncommon findings that may be seen on MR enterography and abdominal CT examinations performed in patients with Crohn's disease include hepatic sinusoidal dilatation, primary sclerosing cholangitis, fistulas in unusual locations, hepatic and splenic abscesses, and spondylarthritis. Radiologists should be aware of these potentially rare manifestations. They should be kept in mind during clinical examinations and should be routinely searched for and reported if present.
