Abstract

Hepatic inflammatory pseudotumor (IPT) is a benign lesion characterized by chronic infiltration of inflammatory cells and fibrosis that clinically, radiologically, and pathologically mimics malignancy. However, the epidemiology of IPTs remains unclear. IPTs are often misdiagnosed as malignant lesions because of the lack of characteristic features. We present the case of a 32-year-old man that was misdiagnosed as intrahepatic cholangiocarcinoma by CECT, CEMRI, and CEUS, which was finally confirmed as IPT by fine-needle liver biopsy. In this report, the key factor in the diagnosis of liver inflammatory masses was the presence of hepatic perfusion disorder.
