An 81-year-old man was referred to our department for an 5-cm tumor occupying the lateral segment of the liver by abdominal ultrasonography at a medical check-up. Further work-up demonstrated dilatation of the intrahepatic bile ducts peripheral to the tumor, no enlarged hepatic hilar lymph nodes and no distant metastatic lesions. Under the suspicion of intrahepatic cholangiocarcinoma of mass-forming type, left hepatectomy was performed.
His postoperative course was uneventful and the patient was discharged on the 8th postoperative day. Macroscopically, the tumor was solid 5cm in size with obscure border and yellowish white. Pathological diagnosis was hepatic IPT.
For IRT, conservative treatment or careful follow-up is the first choice. However, surgery could be considered in case ①symptoms persist, ②major organs are compressed by the tumor, or ③the definitive diagnosis cannot be made (malignancy cannot be ruled out). However, there is no specific findings on imaging studies. In addition, it is difficult to differentiate hepatic IPT from cancer, because the contrast pattern of IPT varies according to time of the inflammation. Hepatic IPT should be included in the differential diagnosis of a liver tumor.
