【摘要】 目的:探讨CT增强扫描及后重建在肠道淋巴瘤中的影像学表现及其诊断价值。材料与方法:回顾性分析经手术病理确诊为淋巴瘤的39例患者的CT资料。结果:39例淋巴瘤患者中,18例发生在小肠,11例发生在大肠,3例累及小肠及临近肠系膜,3例同时累及回肠末段和回盲部,2例累及肠系膜和盲肠,1例同时发生在空肠和回肠,1例累及直肠及乙状结肠。根据肠道淋巴瘤患者的CT表现,可分为4型:①单发肿块型(15),②局部浸润型(14),③弥漫浸润型(8例),④多发病灶型(2例)。结论:CT增强扫描及后重建能较准确地显示肠道淋巴瘤的发病部位、大小形态、强化特点、与邻近结构的关系等,具有较大的应用价值。更多还原

【Abstract】 Purpose:To approach the features of primary intestine tract lymphoma and evaluate CT enhancement scanning and reconstruction in the diagnosis of the disease.Materials and Methods:CT datas in 39 patients with pathologically proved primary intestine tract lymphoma after operation were retrospectively analyzed.Results:There were 39 patients of intestine tract lymphomas.Some were located at small intestine(n=18),large intestine(n=11),both small intestine and mesentery(n=3),involved ileum end piece and ileocecal junction(n=3),concurrenced in mesentery and appendix(n=2),jejunum and ileum(n=1),rectum and sigmoid colon(n=1).According to CT appearances,four types were divided.Single mass was seen in 15 cases.Local infiltration type was occured in 14 cases,diffuse infiltration type was seen in 8 cases.while 2 cases were showed multiple segmental lesion.Conclusion:CT enhancement scanning and postprocessing reconstruction can accurately demonstrate the lymphoma’s situs,size and appearance,feature of enhancement,as well as the relationship with vicinity tissue.CT scan combine with reconstruction is of high value in this disease.更多还原
