Cholangiocellular Ca with multiple foci is a diagnosis of intrahepatic lesions, and the causes of the corresponding conditions mainly include multifocal primary tumor and cholangiocellular Ca with multiple metastases. 1. Multifocal primary tumor: cholangiocellular carcinoma mainly originates from intrahepatic cholangiocellular cells, and the tumor itself will progress along the bile ducts, and some patients will have a mass surrounded by multiple subfoci. 2. Cholangiocellular carcinoma with multiple metastases: some cholangiocellular carcinoma, with the gradual progression of the lesion, may have intrahepatic hematogenous metastases, which may cause corresponding conditions. The appearance of the corresponding conditions, suggesting that the disease is more serious, need to consult a doctor in a timely manner, under the guidance of clinicians for standardized treatment.
