The radiographic appearance at double contrast enema of 33 cases of invasive cancer on adenomatous polyps (AP) of the colon is reviewed. The radiologic diagnosis of malignancy was prospectively made in 54.5% of the cases. In 45.5% of the cases, malignancy was not suspected at the time of examination. The endoscopic appearance of these lesions was identical to that seen on the barium study. There are no radiologic criteria able to entirely rule out the possibility of a carcinomatous transformation of an AP. However, the radiologic features of malignancy (indentation of the intestinal wall and/or irregular outline of the surface of the polyp) have to be considered quite reliable.
回顾了33例结肠腺瘤性息肉（AP）浸润癌的双对比灌肠造影表现。前瞻性地对54.5%的病例做出了恶性肿瘤的放射学诊断。在45.5%的病例中，检查时未怀疑有恶性肿瘤。这些病变的内镜表现与钡剂造影检查所见相同。没有能够完全排除AP发生癌变可能性的放射学标准。然而，恶性肿瘤的放射学特征（肠壁压迹和/或息肉表面轮廓不规则）必须被认为是相当可靠的。
