 Focal area of adynamic ileus close to the appendix location.

Case Discussion

Focal area of adynamic ileus close to the appendix location at right lower quadrant in a patient with abdominal pain and tenderness is compatible with a sentinel loop due to acute appendicitis.

The other common scenario in which a sentinel loop is observed is in acute pancreatitis, the adynamic loop occurring adjacent to potentially any inflamed structure.
