Patient: Description (onset time, main symptoms, hospital visited, etc.): The patient was diagnosed with hepatocellular carcinoma in September this year, and was in the middle and late stages. Today’s ultrasound results are as follows: the surface of the residual liver is still smooth; the right subcostal oblique diameter is 119mm, and the intrahepatic Ohio point is slightly thickened. The echogenic distribution is not uniform. The course of intrahepatic ducts is still clear. The internal diameter of portal vein is about 9mm, which is the blood flow into the liver. The intrahepatic patchy strong echogenic distribution is seen, with a range of about 31x17mm. posterior hemithorax. cDFI shows that no significant heterogeneous blood flow signal is seen. (Ultrasound suggestion) Intrahepatic strong echogenicity (calcification? nodules?) Gynecological examination is normal, no fever, alpha-fetoprotein, carcinoembryonic antigen, aminotransferase, etc. are normal, but there is ascites, please give me an analysis of the possibility of elevated CA125. Hospital Generally speaking, elevated CA125 indicates gynecological diseases, especially malignant tumors such as ovarian and endometrial cancer.
