摘　　要：[目的]探讨直肠腺瘤的CT表现。[方法]对16例经病理证实的直肠腺瘤CT表现进行回顾性分析。[结果]16例腺瘤按病理类型分为绒毛状腺瘤,管状绒毛状腺瘤和管状腺瘤,其中8例恶变。CT征象如下:广基生长有8例,窄基带蒂生长的5例,环壁增厚的有4例;向腔内匍匐式或菜花状生长的有10例;占肠周径比率在1/3以下的9例;病灶与直肠壁相贴时留下通气的间隙7例,可作为直肠腺瘤的特征性表现。[结论]一般直肠腺瘤均具有典型的CT表现,术前明确的腺瘤的CT诊断对于手术方式有重要影响。[Purpose] To investigate CT imaging for rectal adenoma. [Method] CT imaging in 16 cases with rectal adenoma pathologically proved were analysed retrospectively. [Results] The pathological types of 16 cases included villous adenoma, tubulovillous adenoma and tubular adenoma, in which 8 were cancerated.The CT manifestation were as followed： wide base in 8 cases, narrow base with pedicle in 5 cases, the whole paries thickening in 3 cases. Ten cases grew grovelly or cauliflowerly, circumscription of 9 cases were lower than one third of the whole rectal wall. There was a venting gap between the tumour and the opposite wall in 7 cases, which were regarded as the CT characteristic feature for rectal adenoma. [Conclusion ] Most of rectal adenoma have typical CT manifestation, and the definite CT diagnosis of rectal adenoma is important for the choice of operative modaligy.
