We studied 38 superficial-type hyperplastic polyps of more than 0.6cm in size on radiographs to examine their morphologic features. The 38 lesions ranged in size from 0.6cm to 2.5cm, and 22 were located in the sigmoid and transverse colon (Table 1, Fig.1). The cross-section and surface configurations of the 38 lesions studied radiographically are illustrated in Fig. 2. 24 lesions without central depression were classified into 5 groups (1-a to 1-e). The 14 other lesions had central depression (2-a). The cross-section configuration was sharp in all lesions, and a finely serrated arrangement was seen in 30 of them. In surface configuration, several granular patterns were seen, but full-blown undulated folds and/or regular granular patterns were characteristic in groups 1-c, 1-d and 2-a. These radiologic features of cross-section and surface configuration may be regarded as a possible means of distinguishing superficial-type hyperplastic polyps from adenomas and carcinomas of the large intestine.
