We report on a case of an 80‐year‐old male with autopsy‐confirmed biliary cystadenocarcinoma. The tumor's growth was followed up for five years. CT findings on first admission revealed that the cyst walls of the tumor were smooth. However, a CT taken four years later showed large cysts with irregular walls which were growing invasively and expanding beyond the liver. The patient died of liver dysfunction caused by obstructive jaundice due to the liver tumor, and an autopsy was performed. Histologic examination of the autopsy material revealed a multilocular tumor that was identified as being a biliary cystadenocarcinoma and microscopic lung metastases were seen. The character of the multilocular cyst with septations covered by papillary proliferation of atypical columnar epithelium and many remaining portions with low grade dysplasia led us to suspect the tumor was derived from a cystadenoma.
