Figure 10 Active distal ileal Crohn’s disease with complex fistulization and iliopsoas abscess formation. A and B: Coronal; C: Axial fat-suppressed post-gadolinium 3D-GRE T1-weighted images. There is evidence of terminal ilial thickening and enhancement in keeping with active Crohn’s disease, associated with complex ileoileal and ileosigmoidal fistula formation (star sign, arrow, A and B) as well as iliopsoas inflammation and abscess formation (arrowheads, A, B and C). GRE: Gradient recalled echo.
