摘　　要：目的分析膝关节树枝状脂肪瘤的临床、MRI及病理学表现,提高对此疾病的认识。方法回顾性分析2014年3月至2020年3月9例经关节镜手术及术后病理检查证实为树枝状脂肪瘤的临床资料,对影像资料、临床表现及病理结果进行分析。结果9例均发生于髌上囊,表现为膝关节渐进性肿胀和膝关节慢性疼痛。MRI检查T1加权成像(TWI)序列上增厚的滑膜表现为高信号、T2加权成像(T_(2)WI)序列上表现为稍高信号,脂肪抑制序列上为低信号,梯度回波序列上为高、低混杂信号,所有患者均行关节镜探查并镜下关节清理术,术中可见广泛性增厚的髌上囊滑膜组织,以膝关节髌上囊后部重于其他部位,并可见外观呈“棕树叶状”或“绒毛状”改变。诊断均经术后病理证实。结论膝关节树枝状脂肪瘤临床表现是膝关节渐进性肿胀和膝关节慢性疼痛,髌上囊区是其好发部位,MRI有其特征性改变,并可术前对LA做出定性诊断。Objective To analyze the clinical manifestations and MRI features of lipoma arborescens-(LA)of the knee joint,so as to improve the understanding of the disease.Methods From March 2014 to March 2020,9 cases of lipoma arborescens confirmed by arthroscopic surgery and postoperative pathology were retrospectively analyzed.The imaging findings were analyzed and combined with clinical and pathological data.Results All the patients underwent arthroscopic exploration and arthroscopic debridement.During the operation,the synovial tissue of suprapatellar bursa was extensively thickened,and the appearance was"palm leaf'or"villous".The diagnosis was confirmed by pathology.Conclusion the clinical manifestations of lipoma arborescens are progressive swelling and chronic pain of the knee joint.Suprapatellar bursa is the most common site.MRI has its characteristic changes,and can make qualitative diagnosis of La before operation.
