作者对5例胶质二氧化钍症时胆管细胞癌及1例肝细胞与胆管细胞癌混合型癌作了影像学研究。确诊胶质二氧化钍症到发生肿瘤时间平均为44年5个月。CT对6例恶性肿瘤中5例能作出正确诊断,但确诊时肿瘤已增大到不能切除。US对6例中3例能作出诊断。单纯腹部平片无诊断价值。肿瘤标记阴性的胆管细胞癌US及CT对肝右叶前区至肝左叶内侧的镶嵌状胶质二氧化钍肿块能作出诊断,血管造影见右前枝血管呈圆弧状受压及不规则血管增生,并有肿瘤染色。1例肝细胞癌、胆管细胞癌混合型,CT于肿瘤标记阳性初期无异常所见,肿瘤标记迅速升高时,CT见胆囊内有钙乳样胆汁,呈
The authors performed radiological studies on 5 cases of bile duct cell carcinoma and 1 case of mixed hepatocellular and cholangiocarcinoma. The average time from the diagnosis of colloidal guanosine to tumors was 44 years and 5 months. CT can correctly diagnose 5 cases of 6 malignant tumors, but the tumor has been enlarged to be unresectable at the time of diagnosis. The US can make a diagnosis of 3 of 6 cases. Plain abdominal plain films have no diagnostic value. Tumor marker-negative cholangiocarcinoma US and CT can be used to diagnose the mosaic glial ceria masses from the right hepatic lobe anterior to the left hepatic lobe. The angiography shows that the right anterior branch vessels have arc-shaped pressure and irregular blood vessels. Hyperplasia with tumor staining. In 1 case of mixed hepatocellular carcinoma and cholangiocarcinoma, CT showed no abnormalities in the early stage of positive tumor marker. When the tumor marker increased rapidly, CT showed gallstone-like bile in the gallbladder.
