摘要：
BACKGROUND Simple hepatic cysts are relatively common in adults, and mostly appear asasymptomatic incidental radiologic findings. Occasionally, a large cyst will causesymptoms. Elevations in the serum biomarkers protein induced by vitamin Kabsence (PIVKA)-II, cancer antigen (CA) 12-5, and CA19-9 are often associatedwith malignant tumors in the liver or bile ducts. This is the first report to describea case of hepatic cyst with elevated levels of PIVKA-II and CA12-5.CASE SUMMARY An 84-year-old Chinese woman was admitted with gradual abdominal distension.Her symptoms started 1 year ago, and she had poor appetite and a weight loss of5 kg within the past 2 wk. She denied any symptoms associated with abdominalpain, fever and chills, nausea and vomiting, etc. The abdomen was enlarged, morein the right upper quadrant, without tenderness. Laboratory examination showedsignificantly increased serum levels of PIVKA-II, CA12-5, and CA19-9. Acomputed tomography scan revealed multiple round cysts in the liver with clearboundaries. The largest cyst was 20.1 cm × 12.2 cm × 19.6 cm in size, located in theright lobe of the liver with mild dilatation of the intrahepatic bile duct, but therewas no contrast enhancement. Percutaneous drainage on the largest hepatic cystand polycinnamol sclerosing agent injection into the cyst cavity were performed.After treatment, the patient’s symptoms relieved and the elevated serum tumormakers reduced to the normal levels dramatically.CONCLUSION The present report identifies an unusual case of a giant hepatic cyst with markedelevation of serum tumor marker levels of PIVKA-II, CA12-5, and CA19-9. Aftertreatment, these three serum markers dramatically decreased to normal levels.The mechanisms for the elevation of these tumor markers may be as follows: (1) Agiant hepatic cyst compresses the liver, causing injury to the hepatocytes, whichmay lead to secretion of a large amount of PIVKA-II;and (2) Some tumorassociatedantigens, such as carcinoembryonic antigen, CA19-9, CA12-5, andCA15-3, are expresse
