To investigate the imaging manifestation value of multislice CT (MSCT) and magnetic resonance imaging (MRI) in hepatic inflammatory myofibroblastic tumor (HIMT).

Six cases of HIMT were successfully diagnosed by histopathologic examination from February 2015 to November 2017 in People’s Hospital of Leshan. We retrospectively analyzed the clinical features of the cases. Two cases were examined by plain CT scan, four by plain CT scan and enhanced CT scan, four by plain MRI scan and enhanced MRI scan. Enhanced MRI scan was done for all plain CT to analyze tumor location, size, density/signal, shape, presence of cystic, degree and pattern of enhancement.

All the six HIMT cases showed low density in MSCT and uneven in MRI, five cases with blur enhanced edge in arterial phase and one case had no obvious enhanced in arterial phase, while the portal and delayed scanning was significantly enhanced.

MSCT and MRI imaging can clearly display the morphological changes, the degree and patterns of enhancement of the lesions of HIMT. MRI multisequence imaging can be used to determine the possible components of the lesions, especially the necrosis inside the lesions with low signal in T2WI-fat saturation, which has important reference value for accurate diagnosis.
