摘要

The aim of this study is to explore MR features and imaging mechanism of intestinal phytobezoar and to deepen the understanding of intestinal phytobezoar. @@@ Eighteen cases of intestinal phytobezoar (including 15 cases in small intestine and 3 cases in colon) underwent MR examinations. Summing-up and analyzing MR features combinded with intraoperative findings. @@@ All 18 cases of intestinal phytobezoar showed irregular shape low signal on T2-weighted image, which was named coke sign in this study. And on T1-weighted image showed as follows: (i) 12 cases of intestinal phytobezoar (11 in small intestine and 1 in ascending colon) showed internal low signal and peripheral ring-like high signal, which was named empty shell sign in this study, (ii) 4 cases of intestinal phytobezoar (3 in jejunum and 1 in ileum) showed mixed slightly higher signal, and (iii) 2 cases of intestinal phytobezoar (both in colon) showed slightly low signal. @@@ Intestinal phytobezoar presented coke sign on T2-weighted image and complicated signal, more often empty shell sign on T1-weighted image. Correct diagnosis of an intestinal phytobezoar has an instructive value in selection of treatment strategy.
