The imaging manifestations of abdominal inflammatory myofibroblastic tumor / 实用放射学杂志

ABSTRACT

Objective To investigate the CT and MRI manifestations of abdominal inflammatory myofibroblastic tumor (IMT). Methods Imaging and clinical data of 8 cases with IMT which proved by pathology were analyzed retrospectively.5 cases were scaned with contrast medium enhancement CT,and 3 cases with contrast medium enhancement MRI.Results Tumors were located in mesenteric region in 3 cases,in the transverse colon in 1 case,in retroperitoneal space in 1 case,in the small omentum in 1 case, in the omentum in 2 cases.8 cases were all single lesion,5 cases boundaries were demarcated,3 cases boundaries were fuzzy.The maximum diameter of tumors were from 4.6-12.5 cm.The density were uniformin 2 cases,and uneven in 3 cases.3 cases were significantly enhanced on enhanced scanning,2 cases were slight enhanced.1 case was solid soft tissue mass with homogeneous enhancement.2 cases were cystic tumor.The solid part was obvious homogeneous enhancement on enhanced scanning.The cystic areas were not enhancement. Conclusion CT and MRI can clearly demonstrate the location,size,number and the relationship with the surrounding structures of IMT.
