To review the radiologic findings of a rarely reported focal area of acquired cartilage thinning located at the center of the glenoid fossa.
We retrospectively reviewed the medical records of 3 patients, each possessing a bare area of the glenoid detected on magnetic resonance (MR) imaging. A literature search was performed to obtain the most current information regarding this uncommon entity.
Magnetic resonance imaging of the glenoid demonstrated a smoothly marginated subcentimeter area of thinning of the central articular cartilage containing hyperintense joint fluid or contrast in the case with MR arthrography. Arthroscopic correlation was obtained in a single case.
The bare area of the glenoid is an acquired cartilage defect located at the center of the glenoid articular surface. Characteristic findings can be seen on MR imaging. Care should be taken not to mistake this acquired condition for posttraumatic defects of the glenoid articular cartilage.
回顾关于位于肩胛盂窝中心的少见的后天性软骨变薄局灶区域的影像学表现。
我们回顾性分析了3例患者的病历，每例患者在磁共振成像（MR）上均显示肩胛盂有裸露区。进行文献检索以获取有关此罕见实体的最新信息。
肩胛盂的磁共振成像显示，中央关节软骨有一个边缘光滑、直径小于1厘米的变薄区域，在磁共振关节造影的病例中，该区域含有高信号的关节液或造影剂。仅1例病例获得了关节镜检查结果。
肩胛盂裸露区是位于肩胛盂关节面中心的后天性软骨缺损。在磁共振成像上可看到特征性表现。应注意不要将这种后天性情况误诊为肩胛盂关节软骨的创伤后缺损。
