Methods： The clinical, imaging, and pathological data of 18 patients with liver cystadenocarcinoma between January 2000 and December 2004 in our hospital were retrospectively analyzed. Results： The liver cystadeno- carcinoma was seen in males and females （m/f： 9/9）; mean age was 51 years. Ultrasonography revealed cystic parenchymatous mass echoes of fluid predominance with uneven margins. Nonenhanced CT revealed intrahepatic low-density space occupying shadows with nodular protrusions on the margins in all cases. Enhancement CT revealed that part of the nodular protrusions and tissues around the lesions were enhanced and the delayed phase disappeared. 66.67% （12/18） of the lesions were more than 10 cm in diameter. The diagnosis of liver cystadenocarcinoma was confirmed by postoperative pathology in all cases. Of these patients, 12 lesions were in the left lobe, 3 in the right lobe, 1 in the mid lobe, 1 in the right and left lobe, and 1 in the caudate lobe. Of tile 18 patients, 6 had completely resect the cystadenocarcinoma, 2 were surgically explored, one received TAE＋fine needle aspiration cytology＋injection of chemotherapy drugs, and 9 underwent radical hepatectomy＋choledochostomy or T-tube drainage, in which, one patient underwent choledochostomy＋left hepatectomy＋radical gastrectomy for cancer＋lymphadenectomy; one patient underwent resection of the cystadenocarcinoma, who had relapse 20 months after the initial procedure. The patient received repeat reseet for the recurrent cystadenoeareinoma＋eholangio-jejunostomy. Six months later she had another relapse and received repeat reseet （only PMCT） for the recurrent cystadenoearcinoma. The patient died from eholangiopleural fistula after third time operation （PMCT） was attempted perioperatively. Seven patients died of metastatic disease after operation. The remaining 10 patients were alive without cancer recurrence or metastasis （mean follow-up 20 months）. Conclusion： Liver eystadenocarcinoma is rarely seen and grows slowly. It shows some typical clinical and imaging features. The crux for diagnosing and treating liver cystadenoeareinoma is how familiar the surgeon is with the pathology and clinical features of the condition. Prolonged survival can be achieved by radical resection of the tumor.展开更多
