绝大多数踝关节骨软骨病变(损伤)发生在距骨(osteochondral lesions of the talus,OLTs),胫骨远端骨软骨病变(osteochondral lesions of the tibel plafond,OLTPs)约占踝关节骨软骨损伤的2.6%[1-2]。距骨和胫骨发生骨软骨病损的比例为14...绝大多数踝关节骨软骨病变(损伤)发生在距骨(osteochondral lesions of the talus,OLTs),胫骨远端骨软骨病变(osteochondral lesions of the tibel plafond,OLTPs)约占踝关节骨软骨损伤的2.6%[1-2]。距骨和胫骨发生骨软骨病损的比例为14∶1和20∶1[2-4]。Irwin报道距骨软骨病损同时并发胫骨远端骨软骨病损的比率为31%(26/83),其中镜像损伤者占35%(9/26),二者的发生率与年龄呈正相关[5]。胫骨远端骨软骨病损的机制并不清楚,临床症状隐匿,无特异性体征,诊断困难。由于多数胫骨骨软骨损伤伴有踝关节外伤史,因此多数患者都是在检查踝关节损伤或距骨病变时被偶然发现。展开更多

However, early diagnosis and treatment of PAN is necessary to prevent serious organ damage. Herein,we present a boy in whom the diagnosis of classical PAN was established rapidly with ultrasound and computed tomography (CT) angiography. Moreover, complete disappearance of the aneurysms after one month of therapy was documented. This case is presented in order to underline the role of new imaging techniques in the diagnosis and follow-up of patients with PAN.展开更多
