2. Fig. 1
52-year-old woman with ileoileal complex internal fistula associated with stricture.
Coronal T2 – weighted SSFSE image shows stricture (arrow) and distortion of distal ileum. There is considerable luminal dilatation proximal to the stricture. Asterisks indicates converging point of enteroenteric fistula from where bowel loops radiate.

3. Fig. 2 30-year-old man with complex internal fistula.
Coronal SSFP MR image shows collapsed bowel loops intersecting at ileoileal and ileocecal fistula sites (large arrows). Note perienteric mesenteric heterogenity, fat stranding, irregular hypervascularity (small arrows), and spiculations adjacent to the serosal surface of involved terminal and distal ileum.

4. Fig. 3 44-year-old man with surgically verified ileoileal fistula.
Coronal SSFSE MR image shows ileal wall thickening and mural edema associated with fistulous connection between the ileal loops (black arrows). Minimal fluid collection (white arrow) coating the surface of involved bowel segment is also seen.

5. Fig. 4 35-year-old woman with complex ileocecal and ileoileal fistula.
A, Coronal contrast-enhanced fat-suppressed T1- weighted 3D gradient −echo image shows mucosal enhancement (arrow) in the ileal segment which is involved in the internal fistula network. C: Deformed cecum.
B, Coronal T2 – weighted SSFSE image shows ileal wall thickening, cecal contraction (C), and ileocecal valve deformity associated with complex internal fistula.
Asterisks on A and B indicate intersecting point of tracts and bowel loops at fistula site.

6. Fig. 5 39-year-old man with ileosigmoidal and ileoileal fistula.
Coronal contrast-enhanced fat-suppressed T1- weighted 3D gradient – echo image shows arrangement of inflamed bowel loops in a star-like configuration or “stellate pattern” in the circle.
