【摘要】：正原发性小肠淋巴瘤(PSIL)是小肠壁淋巴组织恶性肿瘤。其病因可能与感染、免疫异常等因素有关。由于小肠冗长曲折、互相重叠且不断蠕动,以往采用内镜、钡剂造影等检查方法,均无法观察到管壁及管腔外的变化,诊断准确性较差。螺旋CT密度分辨率高、容积扫描快速、后期处理方便,能够清楚判断腔壁的厚度、病变形态、显示肠系膜及肠腔外的情况等。因此被国内外研究者认为是诊断小肠病变最理想的检查方法〔1,2〕。本研究分析老年PSIL患者的CT资料,总结老年PSIL
[Abstract]:Positive primary small intestinal lymphoma (PSIL) is a malignant tumor of lymphatic tissue in the small intestine wall.Its etiology may be related to infection, immune abnormalities and other factors.Because the small intestine is long and tortuous, overlapping and peristalsis, in the past, using endoscopy, barium radiography and other examination methods, can not observe the changes of the wall and the outside of the tube, the diagnostic accuracy is poor.Spiral CT has high density resolution, rapid volumetric scanning and convenient post-processing. It can clearly judge the thickness of the cavity wall, the shape of lesion, and display the mesenteric and extraluminal conditions.Therefore, it is considered by domestic and foreign researchers to be the most ideal diagnostic method for small intestinal lesions.This study analyzed the CT data of elderly patients with PSIL and summarized the elderly patients with PSIL.
