Methods CT imaging features and pathological results of 22 cases of children who had been pathologically confirmed with abdominal IMT from January 2010 to October 2014 were retrospectively analyzed. Results Most of the tumors were solid without calcification and distributed in the abdominal organs, including the liver, spleen, stomach, gallbladder and duodenum, gastric antrum and peritoneal. The uniform or non-uniform enhancement was revealed in solid lesions through enhanced scanning. While, irregular, annular or circular enhancement was revealed in the mixed areas of cystic and s
