作者回顾了31例确诊的转移瘤,用CT找寻原发癌,大多数病例是腺癌。31例中18例从手术或尸检证实的,13例细胞学证实的。31例病人曾用胸部正、侧位、支气管镜、超声、胃肠检查、钡灌肠、胃镜、结肠镜、CT检查。CT层厚为8～4 mm,甚至2 mm,2/3病例用100～150ml非离子型造影剂困注。19例从肺尖至肾上腺,12例从肝到耻骨联合。以CT表现与常规X线检查对比。18例中16例在CT能检查的范围中,其中6例得出正确诊断。故CT能查出1/3的不引人注意的肿瘤如胸膜间皮瘤、胰腺肿瘤、肾上腺样癌。误诊的有:1例胸膜间皮瘤的范围很小,当做肿瘤引起的胸膜转移,1例是
The authors reviewed 31 confirmed metastases and used CT to find primary cancers. The majority of cases were adenocarcinomas. Of the 31 cases, 18 were confirmed by surgery or autopsy, and 13 were confirmed by cytology. Thirty-one patients had chest, frontal, lateral, bronchoscopy, ultrasound, gastrointestinal examination, barium enema, gastroscopy, colonoscopy, and CT. The CT layer thickness was 8 to 4 mm, even 2 mm, and 2/3 cases were trapped with 100 to 150 ml of non-ionic contrast agent. Nineteen patients ranged from the tip of the lung to the adrenal glands, and 12 cases from the liver to the pubic symphysis. Comparison of CT performance with conventional X-ray examination. Of the 18 cases, 16 were in the scope of CT examination, of which 6 cases were correctly diagnosed. Therefore, CT can detect 1/3 of unobtrusive tumors such as pleural mesothelioma, pancreatic tumor, adrenal carcinoma. Misdiagnosis: 1 case of pleural mesothelioma is very small, as a tumor-induced pleural metastases, 1 case is
