摘　　要：目的探讨肠道非霍奇金氏淋巴瘤的CT和MRI特征表现及其诊断价值。方法回顾性分析15例肠道淋巴瘤的CT和MRI检查资料。全部病例经手术或活检病理证实,均为非何杰金恶性淋巴瘤。结果本组15例共发现不连续肠道病变19个,浸润型病灶11个,其中"动脉瘤样扩张征"5个;肠壁非均匀性增厚型病灶3个;肿块型病灶5个。腹腔淋巴结肿大15例。脾受侵犯5例。结论肠道非霍奇金氏淋巴瘤的CT和MRI表现具有一定特征性,CT和MRI在显示肠管壁形态、增厚的程度与范围,浆膜面的改变,肠外器官的侵犯,淋巴结增大等方面能提供较详细资料,有助于肿瘤的定性、分期及疗效评价。Objective To evaluate CT and MRI features and the diagnostic value of non-Hodgkin＇ s lymphoma of intestinal tract. Methods CT and MRI study of 15 patients with non-Hodgkin＇s lymphoma of intestinal tract were reviewed retrospectively. All cases were confirmed by operation or pathology. Results 19 intestinal focuses were found in 15 patients, with infiltrative type 11 lesions, distending as aneurysm sign 5 lesions, irregular thickening of intestinal wall 3 lesions, mass type 5 lesions. Enlarged cervical lymph nodes were found in 15/15. Spleen involvement was found in 5/15. Conclusion Non-Hodgkin＇s lymphoma of intestinal tract showed characteristic features in CT and MRI scanning. It could provide more detailed information in showing the morphology of bowel wall, the degree and scope of thickened bowel wall, the serosal change, invasion of peri-intestinal organs and enlarged lymph node. It is helpful in qualitation, staging of neoplasm and evaluating the effect of treatment.
