Intrahepatic cholangiocarcinoma imaging shows multiple diffuse hypodense lesions in the liver. Intrahepatic cholangioangiomas are caused by embryonic developmental disorders of the tiny bile ducts in the liver, and appear as cystic foci with a cystic wall composed of bile duct epithelium surrounded by fibrous tissue. Patients usually have no clinical symptoms, and it is usually found during physical examination, surgery or autopsy. Imaging characteristics: CT plain scan shows multiple small low-density cystic lesions in the liver, with no obvious enhancement after enhancement, CT has limited diagnostic value for intrahepatic cholangiocarcinoma. MRI has high sensitivity and specificity, and is regarded as the “gold standard” for the diagnosis of intrahepatic cholangiohepatic malformation tumor.MRI T1WI showed intrahepatic lesions with low signal, and T2WI showed high signal and clear boundary. On magnetic resonance cholangiohydropathy (MRCP), the lesion is diffusely characterized by a small cystic high signal of varying sizes, with an irregular morphology and clear borders, and it is not connected to the biliary tree that drains bile. If the presence of intrahepatic cholangiocarcinoma is detected, it should be promptly diagnosed and standardized.
