Misdiagnostic Analysis of Chondromyxoid Fibrlma in Rare Positions

目的 探讨少见部位软骨粘液样纤维瘤的临床及 X线特征 ,分析误诊原因。方法 回顾分析 8例确诊病例的临床资料 ,复读 X线片。结果 8例中误诊为结核 2例 ,骨囊肿 2例 ,内生软骨瘤 2例 ,骨纤维异常增殖症 2例。掌、指、跟骨病变发现早 ,X线表现有一定特征 ,肋骨病变发现晚 ,X线表现不具特征性。结论 对发生于掌、指、跟骨的病变结合临床 ,仔细阅片、全面分析后术前基本能够确立诊断 ;而肋骨病变则因缺少特征性 ,依靠临床及 X线难以确诊。

Objective To explore the CMF's clinical characteristics and X ray manifestations and analyse the reasons of misdiagnosis.Methods Clinical data of 8 cases of CMF were analyzed retrospectively.Results Among 8cases,2 were misdiagnosed as bone tuberculosis,2 as bone cyst,2 as enchondroma, and 2 as frbrous dysplasia of bone. The diseases located in metacarpal bones, phalanges of fingers and the calcaneus could be found early, and the x ray changes are characteristic .While those in rib swere found later, and the x ray has no significant features. Conclusions The lesions located in metacarpal bones, phalanges of fingers and the calcaneus could be diagnosed correctly before the operation as long as doctors read the X ray pictures carefully and analyzed thoroughly patients′ conditions.While those located in ribs were difficult to diagnose because of lack of characteristics.
