Fig. 4. A 5-cm intra-abdominal abscess in a 22-year-old male patient with Crohn’s disease. Postcontrast-enhanced axial (A) and coronal (B) computed tomography images show fluid and air-containing abscesses (arrows) with rim enhancement in the adjacent pelvic loop of ileum. Coronal image demonstrates mild wall thickening and asymmetric mural hyperenhancement (arrowhead) along the mesenteric border of the pelvic ileal loop, consistent with active inflammatory Crohn’s disease.
