Imaging performance of hepatic inflammatory myofibroblastic tumor / 中国医学影像技术

Objective To assess the radiological imaging findings of hepatic inflammatory myofibroblastic tumor and to discuss the appropriate morphological classification.Methods A total of 22 patients with hepatic inflammatory myofibroblastic tumor confirmed by pathology were enrolled.Imaging performance of hepatic inflammatory myofibroblastic tumor were analyzed and the lesions were classified into appropriate type based on the imaging findings.Results Totally 23 lesions were found in 22 patients.The typical imaging features included great enhancement at later phase (13/20),moth eat en central necrosis (12/23) and peripheral shell (12/23).Seed in fruit was the most typical classification (8/23),followed by Seedless fruit (7/23).Conclusion Hepatic inflammatory myofibroblastic tumur typically shows as a single nodular lesion with moth eaten necrosis and peripheral shell like a Seed in fruit.The enhancement at later phase (especially the peripheral enhancement) can be regarded as a particular feature.
