Pseudosacculations (also known as pseudodiverticulae) are outpouchings of normal bowel wall along the antimesenteric border. Inflammation and fibrosis along the mesenteric border of the bowel loop causes asymmetric shortening of the mesenteric wall, and subsequent pseudosacculations of the normal antimesenteric wall 1,2.
Pseudosacculations are typically seen in Crohn disease, however can also be seen in scleroderma.
