1、V腹部放射学A原发性大肠淋巴瘤的CT检查价值赵修义,张雪林,郑卫权,王劲,文戈【摘要】目的探讨原发性大肠淋巴瘤的CT表现及其诊断价值。资料与方法复习经病理证实的8例原发性大肠淋巴瘤CT资料。所有病例均行常规腹部CT平扫,6例加作增强扫描,扫描层厚、层距为5-10mmo结果8例原发性大肠淋巴瘤发病部位有肠3例,升结肠2例,直肠1例,大肠弥漫浸润2例。CT表现主要包括3种主要类型。局灶性肿块型2例,其中1例伴有肠套叠及腹膜后淋巴结肿大;节段环形浸润型3例,其中1例伴有肠系膜淋巴节肿大;弥浸浸润型2例,呈多发节段性分布,累及整个结肠,并伴有肠系膜床巴结肿大;直肠内的多发结节1例。结论CT
2、能较准确地显示淋巴瘤的发病部位、并发症及与邻近结构的关系;局灶性肿块型、节段环形浸润型及弥浸浸润型是大肠滞巴瘤的3种主要CT表现类型;正确辨认大肠淋巴瘤的CT表现,对部分病例可做岀提示性诊断。【关键词】淋巴瘤,诊断大肠体层摄影术,X线计算机EvaluationofCTSnninginDiagnosingPrimaryLargeIntestineLymphomasZHAOXiuyi>ZHANGXuelin,ZHENGWeiquan,etal.DiagnosticImagingCenter,NanfangHospitaltNo.1MilitaryMedicalUniversity,Gu
