摘　　要：目的：探讨Osgood-Schlatter 病（OSD）的 CT 及 MRI 表现,并对其分期进行初步探索。方法收集27例 OSD 患者的影像资料,对其 MRI 及 CT 表现进行回顾性分析。结果27例患者均表现为髌韧带下部的不同程度增宽及不同范围的水肿。5例表现为胫骨结节骨骺及干骺端的骨质水肿；15例胫骨结节骨质增生、不光整,其中5例呈“开贝”样改变；7例表现为髌韧带下部内孤立性骨化结节的形成,其中1例胫骨结节骨质膨隆肥大。其中3例患者行 CT 平扫可见髌韧带下部内的骨化结节。结论OSD具有特征性的 CT 及 MRI 表现,MRI 可显示髌韧带的形态及信号、骨质水肿情况,有助于对 OSD 进行分期及对预后进行评估。Objective To characterize the CT and MRI features of Osgood-Schlatter disease （OSD）,and explore the feasibility of staging OSD by using CT and MRI.Methods The imaging data of the 27 cases with OSD were retrospectively analyzed,and features of MRI and CT were characterized.Results All 27 cases with OSD were featured with different extent of edema within the patellar tendon.The portion already exhibited edema in the secondary ossification center in 5 cases,which showed high signal intensity on the T2 WI.There were 1 5 cases which exhibited ossified or tears in the secondary ossification center,and 5 of them were featured with opened shell-like separation on sagittal radiograph.Seven cases had isolated solitary ossicles located at the lower part of the patellar ligament,which is also thickening.Among the 7 cases,one showed hypertrophy in the tibial tuberosity.Three cases examined with CT scan,exhibited ossified nodules located at the lower part of the patellar ligament.Conclusion OSD has characteristic CT and MRI features,and MRI scan is an important imaging method to show edema and morphological changes of patellar tendon in OSD,which could help to identify the stage of OSD and predict the prognosis.
