Abstract：Objective: To evluate the CT imaging features of hepatic inflammatory myofibroblastic tumor(HIMT), so as to improve its diagnostic accuracy. Materials and Methods: The clinical and CT imaging findings of 6 cases of HIMT which confirmed by pathology in our hospital were analyzed retrospectively, including 4 males and 2 females, aged from 48 to 59 years old, mean age was 43 years old. Pre- and post-contrast CT images were examined for all six cases. Results: Five of six cases were single lesion, the other one was multiple. Clear margin was in four cases and unclear margin in two cases. Three cases were located in the left lobe of liver, 2 cases were in the right lobe of the liver and 1 case was located both the left and right lobe. In the pre-contrasted enhancement CT scan, heterogeneous(n=2) or homogeneous(n=4) hypo-density were shown in six cases. No enhancement(n=2) or mild/moderate enhancement(n=4) was shown in arterial phase respectively. Delayed enhancement was shown in the portal phase(n=6) and the delayed phase(n=5). Moreover, on the arterial phase image, feeding artery were shown in one case, having patchy enhancement around it in one case. The dilatation of the intra-hepatic bile duct was seen in one case. Conclusion: The dynamic contrast enhancement CT features of HIMT are multiple characteristic, which correlate with its pathologic findings. But the final diagnosis relies on pathology and immunohistochemistry examination.
