摘要
目的：复习大肠淋巴瘤的影像学表现，以期对原发大肠淋巴瘤在术前提出诊断，尽早发现继发大肠淋巴瘤。材料与方法：１７例经手术或活检证实的大肠淋巴瘤，行钡剂或双对比灌肠造影１６例，ＣＴ扫描９例。结果：１７例均为非何杰金淋巴瘤，原发５例，继发５例，初诊时即属Ⅳ期７例。病变累及１段结肠１２例，同时或先后有多于１段结肠受累５例。钡灌肠造影见扁平盘状隆起２例，孤立结节１例（２个），单发肿物６例，肠腔狭窄８例，全部结肠多发结节伴回盲部全周狭窄１例。ＣＴ扫描见肠壁增厚４例，结节或肿块４例，腹腔、盆腔、腹膜后淋巴结肿大３例，肝、脾受侵及回盲部肠套叠各１例。结论：钡灌肠及ＣＴ扫描是互补的检查方法，分别提供粘膜及肠壁和肠外的病变情况。大肠淋巴瘤常表现为轮廓光整的结节或肿物（４７％），肠壁增厚（４７％），肿大淋巴结（３３．３％）。病变罕见向周围脂肪浸润。
Objective The objective is to review the imaging features of large intestine lymphoma,in order to improve the diagnostic accuracy of primary lymphoma before surgery and the early detection of secondary lymphoma,Materials and Methods:17 cases of pathology proved large intestine lymphoma were reviewed,16 cases had double contrast barium enema and 9 cases had CT scans. Results:Of the 17 cases reviewed,lesions were found in rectum(n=8,47%),terminal ileum and caecum(n=7,41%).5 cases had more than one segment of colon invaded synchronously or metachronously. 5 cases had primary and 5 cases had secondary large intestine lymphoma,7 cases were presented as stage Ⅳ. In barium enema,there were stricture of intestinal lumen(n=8),single mass lesion(n=6),disc-like lesion (n=2),and two discrete nodules(n=1).In CT scanning,there were thickening of the intestine wall(n=4),nodule or mass(n=4),retroperitoneal,intra-abdominal and/or intrapelvic lymphadenopathy(n=3),liver,spleen involvement,ileal-cecal intussusception for one each.Conclusion:Double contrast barium enema and CT scanning are recommended since they are complementary in demonstrating intra-luminal and extra-intestinal lesions,and intestinal wall thickening. The accuracy of staging can be improved.
