目的：目的：探讨颞下颌关节（TMJ）滑膜软骨瘤病（SC）的MRI表现类型及其潜在的攻击行为。MRI表现为3种类型：游离体、均匀性肿块、游离体与均匀性肿块混合。结果：骨质疏松型47例（32.6%），均质型71例（49.3%），混合型26例（18.1%）。骨穿孔均质型占80%，混合型占20%。结论：MRI表现为均匀性肿块及两者混合型者，其侵袭性更强。MRI显示骨质侵蚀的均质肿块有复发的可能。(C)2015年欧洲颅颌面外科协会。由爱思唯尔有限公司出版。保留所有权利。
Purpose: To evaluate the types of synovial condromatosis (SC) of tempromandibular joint (TMJ) on MRI and their potential aggressive behavior.Methods: 144 patients with pure SC of TMJ were included in. On MRI, 3 types of the lesion included loose body, homogeneous mass, and mixture of both loose body and homogeneous mass. Bony evaluations included 4 stages of erosion: without erosion, chondral breakdown, bony absorption and bony perforation.Results: 47 (32.6%) cases were categorized in the type of loose body, 71(49.3%) cases in the type of homogeneous mass, and 26(18,1%) cases in the type of mixture. 80% of bony perforation belonged to the type of homogeneous mass and 20% belonged to the type of mixture. 2 patients were found recurrence.Conclusion: The types of homogeneous mass and mixture of both on MRI were more aggressive. Homogeneous mass with bony erosion on MRI had potential recurrence. (C) 2015 European Association for Cranio-Maxillo-Facial Surgery. Published by Elsevier Ltd. All rights reserved.
