Crohn’s disease is an autoimmune disease affecting over 3 million people in North America. Radiology plays an important role for diagnosing, evaluating treatment response, and guiding surgical management in these patients. In particular, Crohn’s patients with active inflammatory disease are often symptomatic and require diagnostic imaging. Active inflammatory disease can lead to stricturing and transmural ulceration, which lead to sinus tract, abscess, and fistula formation. These complications are often complex and can be challenging for radiologists to interpret. For this reason, it is important for general and abdominal radiologists to be familiar with the imaging appearance of active inflammatory Crohn”s along with the stricturing and penetrating complications.

Educational Goals / Teaching Points
After reviewing this exhibit, the participant should recognize the imaging features of Crohn’s disease; understand the mechanism of active inflammatory Crohn’s disease progressing into stricturing and penetrating Crohn’s disease; and recognize the imaging appearance of stricturing and penetrating complications of Crohn”s disease.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
Key imaging findings of Crohn's disease and signs of stricturing and penetrating Crohn's Disease, including sinus tract, fistula, and abscess, are presented, as well as imaging of other sequela and complications of active inflammatory Crohn’s.

Imaging of patients with active inflammatory Crohn's disease is becoming increasingly common, especially in the acute setting. Our gastroenterology and surgical colleagues rely heavily on our imaging expertise to help guide management. It is important for radiologists who interpret abdominal imaging to know the imaging features seen with Crohn's disease, especially active inflammatory Crohn's and the associated stricturing and penetrating disease.
