Usefulness of multi-slice CT in a case with internal fistulas in Crohn's disease

A case of Crohn's disease with an ileo-ileo fistula, ileal strictures and an ileo-cyst fistula is reported. Laparoscopic operation that included partial ileoectonly, ileal stricturoplasty and dissection of the ileo-cyst fistula was performed. Multi-slice computed tomography (MSCT) that was performed before the operation showed an ileo-cyst fistula that was not detected by small bowel follow-through or MRI. In this case, MSCT, including multi-planar reconstruction images, was significantly useful for evaluation of internal fistulas in Crohns disease.
