Abstract:
Objective To describe the CT and MR imaging features of hepatic inflammatory myofibroblastic tumor(IMT).Methods The CT(n=12)and MRI(n=2)findings of pathologically proved hepatic IMT in 12 patients were retrospectively analyzed.Results All the tumors of the 12 patients were solitary and located in right hepatic lobe.Six tumors were solid and 4 tumors were solid-cystic.The other 2 tumors were periportal soft-tissue infiltration.The tumors appeared as solid or solid-cystic hypodense mass on CT images.The lesions were dark in T1-weighted sequences and slightly bright on T2-weighted sequences.There was homogeneous or inhomogeneous moderate to significant enhancement in solid portion of the tumors.Honeycomb-like enhancement was demontrated both in the peripheral part and at the intratumoral septa of the solid-cystic mass.Conclusion CT and MRI can provide helpful information for the clinical diagnosis and differential diagnosis of hepatic IMT.
