摘　　要：目的探讨表现为腹膜后间隙孤立性肿块的淋巴瘤的CT特点及其解剖学基础。方法回顾40例病理诊断明确的表现为腹膜后间隙孤立性肿块的淋巴瘤的CT资料,探究其影像解剖学特点。结果本研究中的淋巴瘤有两种类型:单纯肿块型(n=13)和单发肿块伴周围多发肿大淋巴结型(n=27),两种类型肿块在有无包绕血管(P=0.004)、主动脉漂浮征(P=0.001)方面有统计学差异,其短径(P=0.230)、解剖位置(P=0.427)、CT强化程度(P=0.184)、强化均匀度(P=0.933)、肿块边界(P=0.408)等无统计学差异。结论CT对腹膜后间隙孤立肿块型淋巴瘤的诊断及其解剖学细节的显示具有重要作用,可为腹部淋巴瘤的诊断和鉴别诊断提供影像学依据。Objective To investigate the CT characteristics and anatomical basis of lymphoma with solitary mass in retroperitoneal space.Methods The CT data of 40 cases of lymphoma with solitary retroperitoneal mass confirmed by pathological diagnosis were reviewed retrospectively to study and explore the imaging anatomic features.Results The retroperitoneal lymphoma in this study could be divided into two types:(1)solitary retroperitoneal mass type(n=13)(2)single dominant retroperitoneal mass surrounded by enlarged lymph nodes type(n=27).There were statistical differences between the two types of masses in whether they were surrounded by blood vessels or not(P=0.004)and whether they had aortic floating signs or not(P=0.001).There was no statistical difference in terms of the short-axis diameter of the masses(P=0.230),the masses’anatomic location(P=0.427),CT enhanced degree(P=0.184),homogeneous enhancement or heterogeneous enhancement(P=0.933),margin of the mass clear or not(P=0.408)between these two groups.Conclusions CT plays an important role in the diagnosis and anatomical details of solitary mass lymphoma in retroperitoneal space.It can provide imaging reference for the diagnosis and differential diagnosis of abdominal lymphoma.
