Spontaneous ECF in a 37-year-old man with stricturing and fistulising CD, shown at MR-enterography as a fluid-like T2-hyperintense track (arrows in A) coursing from an ileal loop through the abdominal wall, and finally reaching the EFO (arrowheads). Post-gadolinium fat-suppressed T1-weighted acquisition (B) showed mucosal hyperenhancement along ECF track (thin arrows) and at site of internal opening (*). Surgical treatment required fistula debridement plus stricturoplasty
