摘　　要：目的探讨晚发型脊柱骨骺发育不良伴进行性骨关节病(SEDT-PA)的影像学表现及其病理基础。资料与方法搜集经临床及影像学检查确诊的SEDT-PA同胞姊妹3例,摄双手及腕关节、双肘关节、双髋关节正位X线片,双膝关节及脊柱正侧位片;均行胸腰椎MRI扫描。结果X线片及MRI片均可见椎体变扁,呈"横置花瓶"状和"子弹头"状改变,椎间隙明显变窄。X线片上表现为关节间隙变狭窄,骨端膨大及明显骨质增生。MRI上可见椎间盘变薄,纤维环和髓核结构不能分辨。结论根据特征性的影像学表现,结合临床特点能够明确SEDT-PA的诊断。Objective To investigate the image feature and the pathology of spondyloepiphyseal dysplasia tarda with progressive arthopathy （SEDT-PA）. Materials and Methods Three cases of compatriot sisters with SEDT-PA were confirmed by clinical findings and radiological examination. Frontal projections of bilateral hands,wrists,elbows, hips, frontal and lateral projections od spine and MRI of spine were performed in all cases. Results Vertebra flattened like ＂thwartwise vase＂ or ＂bullet＂ and intervertebral space obviously narrowed were showed. The structure of annulus fibrosus and nucleus pulposus could not be detected on MRI. Joint space narrowing, capitulum enlargement, and obvious hyperostegency were demonstrated on X-ray films. Conclusion The dignosis of SEDT-PA could be made acutely by radiographic features and clinical findings.
