The objective of this study was to examine the prevalence of incidental shoulder enchondromas on routine magnetic resonance (MR) shoulder imaging. Consecutive routine shoulder MR examinations (N = 477) performed for suspected internal derangement were reviewed for the presence of incidental enchondromas. Incidental enchondromas were detected on 2.1% of routine MR shoulder examinations, the vast majority abutting the physeal plate. This prevalence is important to appreciate, in order to form a meaningful differential diagnosis of pathologic proximal humerus lesions.
本研究旨在探讨常规磁共振（MR）肩成像中偶然发现的肩软骨瘤的患病率。回顾了为疑似内部紊乱而进行的连续常规肩 MR 检查（N = 477），以检查偶然发现的软骨瘤的存在。在 2.1%的常规 MR 肩部检查中发现了偶然的软骨瘤，绝大多数与骺板相邻。了解这一患病率非常重要，以便对病理性肱骨头近端病变进行有意义的鉴别诊断。
