Example of pseudosacculation: coronal True FISP image shows two long skip lesions in the mid to distal ileum (asterisk) demonstrating mural thickening, luminal narrowing and prominence of the vasa recta (arrowheads) with small nodes seen within the mesentery. There are multiple pseudosacculations (arrows) on the antimesenteric border due to asymmetric involvement of the bowel wall. Mesenteric fibrofatty proliferation separates the involved bowel loops. Appearances suggest a mixture of active and fibrostenotic disease
