Abstract: Objective To investigate the CT features of mesenteric lymph nodes in patients with active Crohn’s disease.Methods The CT findings in 54 patients with active Crohn's disease proved by histology were analyzed,and the anatomic distribution,size, number,shape and enhancement ratio (ER)of the mesenteric lymph node were assessed.Results Mesenteric lymphadenopathy in 38 patients (70.4%)was found with a total number of 242,83.5%(202/242)of whom were located at the mesenteric root and 16.5%(40/242) at mesenteric edge.The size of the lymph nodes at the mesenteric root was larger than that at the mesenteric edge (8.57 mm±2.26 mm versus 5.38 mm±0.1 9 mm,the mean maximum short diameter),and 73.6% (1 78/242 )of the lymph nodes were oval in shape.The lymph nodes showed significant enhancement after contrast injection with an ER of 0.53 ±0.09.Conclusion Active CD often leads to mesenteric lymphadenopathy,which is more obvious at the mesenteric root.
