Objective: To discuss the myxoadenocarcinoma MSCT sign difference in stomach and intestine. Methods: Retrospective analysis the MSCT signs and clinical data of 30 cases of myxoadenocarcinoma, 15 cases of gastric myxoadenocarcinoma, 15 cases of intestine myxoadenocarcinoma, the MSCT signs were summarized and comparison. Results: Gastric myxoadenocarcinoma not tended to form a mass (15/15), the gastric mucosa integrity rate was 93.3% (14/15), the enhancement curve mainly is Speed up-Balanced type (12/15). Intestine myxoadenocarcinoma tended to form a mass (14/15), mass density were uneven and uneven enhancement (15/15), the enhancement curve mainly is Speed up-Balanced type (10/15). There is no statistical significance on enhancement ways of mucous adenocarcinoma at different positions (P>0.05). There were significant difference between gastric myxoadenocarcinomaand intestine in morphology and integrity (P<0.05). Conclusion: The myxoadenocarcinoma MSCT sign difference in stomach and intestine show in morphology and integrity. The gastric mucinous have the biological features of infiltrative growth, density homogeneous.%目的:对比分析胃肠道粘液腺癌的影像学特征,以提高临床认识.方法:回顾性分析15例经手术病理证实的胃粘液腺癌临床及其影像学资料作为研究组,另选择手术病理证实的肠粘液腺癌15例作为对照组,对比分析不同部位粘液腺癌影像学特征.结果:胃粘液腺癌一般不形成类圆形软组织肿块(15/15);肿块密度相对均匀,增强扫描呈均匀明显强化(14/15);强化曲线以速升平衡型为主(12/15);肠粘液腺癌多表现为类圆形软组织肿块(14/15),肿块密度不均匀,增强扫描呈不均匀明显强化(15/15),强化曲线以速升平衡型为主(10/15);不同部位粘液腺癌强化方式无统计学意义(P>0.05),在形态学、密度方面差异具有统计学意义(P<0.05).结论:不同部位粘液腺癌在形态学及密度方面存在差异;胃粘液腺癌更容易浸润生长,密度相对均匀,不易形成类圆形软组织肿块.
