Fig. 1. A 3-cm intra-abdominal abscess in a 38-year-old male patient with Crohn’s disease. Postcontrast-enhanced axial (A) and coronal (B) computed tomography images show fluid and air collection with rim enhancement in the right lower quadrant mesentery, consistent with an intra-abdominal abscess (white arrows). Multifocal segmental mural hyperenhancement (white arrowheads) and increased mesenteric vascularity (“comb sign”) with enlarged mesenteric lymph nodes (black arrow) are noted in the involved segment of the distal and terminal ileum. These findings are suggestive of active Crohn’s disease.
