Abstract：Objective To investigate the imaging features of Hepatic inflammatory myofibroblastic tumor (HIM T ) and to improve the diagnosis .Methods Seven patients with pathology proved HIMT were reviewed retrospectively .CT scan was performed in 4 patients and MRI was performed in other 3 patients .Results Totally ,7 lesions were found in 7 pa-tients .5 lesions were in right lobe ,2 lesions were in left lobe .Slight low or low-density appeared on CT plain scanning , MRI was manifested as slightly low signal intensity lesions on enhanced T1WI and isointensity or mild hyper intensity on enhanced T2 WI .2 cases were significantly enhanced in arterial phase ,4 lesions were shown mild to moderate enhance-ment ,1 case was shown no enhancement .Portal venous phase showed and delayed phase continuous enhancement in 6 ca-ses ,edge enhancement in 1 case .Conclusion The imaging manifestations of HIMT were miscellaneous ,isointensity or mild hyper intensity on enhanced T2 WI ,dynamic enhancement in portal venous phase and delayed phase continued to strengthen with certain characteristics .As it is a rare disease ,the final decision depends on pathological and immunohisto-chemical examination .
