Crohn disease on MR enterography

Case contributed by Dr Chris O'Donnell

Presentation

8 months of abdominal symptoms with elevated calprotectin suggestive of Crohn disease

Patient Data

Age: 13
Gender: Female
MRI

MR enterography performed in order to avoid ionizing radiation exposure

This study shows all the features of Crohn disease, i.e. circumferential ileal wall thickening with abnormal enhancement and inflammation in the adjacent mesentery (comb sign)

Case Discussion

MR enterography has the advantage (over CT enteroclysis and barium follow-through) of no ionizing radiation and can show features of increased disease activity including wall thickening of greater than 4 mm, intramural and mesenteric edema, wall enhancement, fistula formation, and mesenteric vascular engorgement with inflammed mesenteric lymph nodes.
