A 55-year-old woman admitted for high fever and hypotension was found in US, CT, and MRI to have a giant cystic mass at the left hepatic lobe and ascites. An ascites puncture suggested hepatic rupture, necessitating abdominal drainage. After she recovered, we conducted left hepatic lobectomy due to suspected cystadenocarcinama. The resected specimen showed a multilocular cyst without mural nodules containing pus, mucus, and coagulation fluid. Based on the results of histopathological and immunohistochemical studies, the tumor was definitively diagnosed as hepatic cystadenocarcinoma with mesenchymal stroma. The rupture was complicated by cystadenocarcinoma infection. Hepatic ruptured cystadenocarcinoma is rare.

Key words
