PURPOSE To evaluate and characterize anterior chest wall (ACW) joint's enthesopathy on CT scans in patients with DISH compared with age- and gender-matched control group. MATERIAL AND METHODS Retrospective evaluation for enthesopathy features of ACW joints-sterno-clavicular (SCJ), manubrio-sternal (MSJ), costo-sternal 1-7 (CSJ)-on chest CT scans of subjects with DISH (Resnick criteria) and of age- and gender-matched control subjects was performed. 183 subjects (DISH: 92, control: 91); male:female: 126:57, average age: 71.7 years (range 50-94) were evaluated. Total enthesopathy scores per subjects and per each joint were compared. RESULTS Total enthesopathy score of ACW joints was significantly higher among DISH compared to controls (64.03 ± 15.1, 50.47 ± 12.4, p < 0.001). At joint level, SCJ and CSJ enthesopathy, but not MSJ was significantly more prevalent in DISH compared to controls. CONCLUSION ACW joints' enthesopathy as seen on CT scans, an entity not included in the Resnick classification criteria, is common among DISH subjects. The difference between SCJ and CSJ prevalence compared to MSJ may result from different joint type. ACW joints' enthesopathy may be considered to be included in future modified radiographic criteria for DISH.

弥散性特发性骨骼肥大症（DISH）患者前胸壁关节的病变：计算机断层扫描的回顾性分析。

目的与年龄和性别匹配的对照组相比，在DISH患者的CT扫描中评估和表征前胸壁（ACW）关节的病变。材料与方法回顾性评估DISH（Resnick标准）的受试者的胸部CT扫描-锁骨锁骨（SCJ），腕骨胸骨（MSJ），肋骨胸骨1-7（CSJ）的ACW关节病的特征进行年龄和性别匹配的对照受试者。183名（DISH：92，对照：91）; 男性：女性：126：57，平均年龄：71.7岁（范围50-94）。比较每个受试者和每个关节的总感觉病评分。结果与对照组相比，DISH中ACW关节的总感觉病评分明显更高（64.03±15.1，50.47±12.4，p <0.001）。在关节层面，SCJ和CSJ的神经病，但与对照组相比，DJ中MSJ的流行率没有明显提高。结论在DISH受试者中，CT扫描显示ACW关节的关节病是Resnick分类标准中未包括的实体，这很普遍。与MSJ相比，SCJ和CSJ患病率之间的差异可能是由于关节类型不同引起的。ACW关节的病变可能被认为包含在将来的DISH放射线照相标准中。
