A Case of Hepatic Duct Carcinoma with Hypervascularity in Angiography

It is comparatively rare to see a trachychromatic image of the tumor in an angiogram of an extrahepatic cholangiocarcinoma, but we experienced one case of extrahepatic cholangiocarcinoma with a trachromatic image. The patient was a 68-year-old male with upper abdomnal pain as the main complaint. After liver dysfunction was detected and he was hospitalized, cholangiocarcinoma was diagnosed on the basis of the results of a detailed examination. The histopathological diagnosis was papillary adenocarcinoma. As a result of an investigation of the cause of the trachychromatic image of the tumor, it was found that propagation of capillarie in the interstitium of this tumor was excellent, as revealed by pooling of contrast medium in the capillaries. The tumor base tissue was considered to be a gastrointestinal origin embryologically.
