Abstract

OBJECTIVE

The purpose of this study was to define MR imaging of patients with lipoma arborescens of the knee.

CONCLUSION

MR images showed villous lipomatous proliferation (100%) with signal intensity similar to that of fat on T1- and T2-weighted images, masslike subsynovial fat deposition (38%), joint effusion (100%), erosive bone changes at articular margins (38%), associated synovial cysts (25%), and degenerative changes (13%). MR imaging is a valuable technique for examining patients with lipoma arborescens of the knee and can support the diagnosis of this rare condition.

摘要

目的

本研究的目的是明确膝关节树枝状脂肪瘤患者的磁共振成像表现。

结论

磁共振图像显示绒毛状脂肪瘤样增生（100%），在T1加权和T2加权图像上信号强度与脂肪相似，滑膜下脂肪呈肿块样沉积（38%），关节积液（100%），关节边缘侵蚀性骨质改变（38%），相关滑膜囊肿（25%），以及退变改变（13%）。磁共振成像对于检查膝关节树枝状脂肪瘤患者是一种有价值的技术，能够辅助诊断这种罕见疾病。
