【摘要】 目的探讨CT对同盲部原发恶性非霍奇金淋巴瘤(primary malignant non-Hodgkin-Lymphoma of ileocecum,PMNHLI)的诊断及鉴别诊断的意义。方法回顾性分析2000年12月至2008年7月经CT检查并手术病理证实的PMNHLI11例CT表现,并分析鉴别诊断的意义。结果CT表现以肠壁浸润性增厚(n=4)和类圆形肿块(n=4)多见,也可表现为多发结节(n=1),因肠套叠而漏诊1例,肿块与肠系膜肿大淋巴结融合1例。区域肠系膜多发淋巴结肿大(n=4)、肠套叠(n=4)、不完全性肠梗阻(n=5)为灶外常见表现。CT诊断正确4例,误诊为结肠癌3例、肠系膜肿瘤、肠腺瘤、脓肿各1例,漏诊1例。结论PMNHLI术前诊断困难,CT表现多样,肠内类圆形肿块为常见表现,如以上征象合并区域肠系膜淋巴结多发肿大则可考虑PMNHLI诊断。更多还原

【Abstract】 Objective To evaluate the CT characteristics and differential diagnosis characteristics of primary malignant non-Hodgkin -Lymphoma of ileocecum(PMNHLI).Methods The CT findings of 11 cases of PMNHLI from DEC-2000 to JUL-2008 were retrospectively analyzed.Results The CT findings included:Diffuse thickness of ileocecal wall(4 cases),round or oval soft tissue masses (4 cases),multiple soft tissue nodes(1 case).Missed-diagnosis because of intussusception in one case,and lesion coalesced with enlarged lymph nodes into masses in one case.The appended findings of the lesions included:multiple enlarged lymph nodes of the regional mesentery(4 cases),intussusception(4 cases),and incomplete intestinal obstructions(5 cases).CT diagnosed correctly in 4 cases, misdiagnosed as colon carcinoma in three cases,as mesenteric tumor,adenoma,abscess in one case respectively,and the other one was miss-diagnosed because of intussusception.Conclusion It’s difficult to diagnose the PMNHLI pre-operation.CT findings of PMNHLI are variable.Round or oval soft tissue mass is the common sign.Multiple enlarged lymph nodes of the regional mesentery are useful signs.更多还原
