【摘要】：目的:探讨结直肠原发神经内分泌癌(NECs)的CT征象,以提高结直肠原发NECs的术前诊断。方法 :回顾性分析经病理确诊的32例原发性结直肠NECs患者和46例结直肠腺癌患者的CT表现,比较两组患者发病年龄、性别、肿瘤发生部位、病变大小、肠壁增厚形式、平扫、增强CT值、肠周浸润情况、有无肠梗阻及其他器官转移等的差异。结果:与结直肠腺癌组比较,结直肠原发NECs组患者发病年龄小(t=3.634,P0.001),两组在肠壁增厚形式、病灶大小、病灶强化程度等方面差异有统计学意义(P0.05),在性别、病灶发生部位、有无肠梗阻、有无区域淋巴结转移、有远处转移等方面差异无统计学意义(P0.05)。结论:结直肠NECs发病年龄较轻,其CT表现为息肉/肿块样病灶,密度均匀,增强动脉期表现为中度或显著强化,静脉期进一步强化时,应考虑到结直肠NECs的可能,并可出现显著强化的肝脏转移病灶。
[Abstract]:Objective: to investigate the CT features of colorectal primary neuroendocrine carcinoma (NECs) in order to improve the preoperative diagnosis of colorectal primary NECs.Methods: Ct findings of 32 patients with primary colorectal NECs and 46 patients with colorectal adenocarcinoma were retrospectively analyzed. The age, sex, location of tumor, size of lesion, thickening of intestinal wall and plain scan were compared between the two groups.Enhanced CT value, periintestinal infiltration, intestinal obstruction and other organ metastasis were different.Results: compared with the colorectal adenocarcinoma group, the age of colorectal primary NECs patients was 3.634% P 0.001. There were significant differences between the two groups in the form of thickening of intestinal wall, the size of lesions and the degree of enhancement of lesions, and there were significant differences between the two groups in sex and location of lesions.There was no significant difference in intestinal obstruction, regional lymph node metastasis and distant metastasis.Conclusion: Colorectal NECs has a younger onset age, and its CT features are polyp / tumor-like lesions with homogeneous density, moderate or significant enhancement in the enhanced arterial phase, and the possibility of colorectal NECs should be taken into account in the further enhancement of the venous phase.The liver metastases can be enhanced significantly.
