特发性含铁血黄素沉着症影像诊断分析

目的：探讨特发性含铁血黄素沉着症X线、CT影像表现特征。方法：收集1998年-2005年经胸部X线、CT检奁，最后经实验室检查证实明确诊断为本病的9例进行分析。结果：经实验室检查证实的9例中，初次影像诊断特发性含铁血黄素沉着症仅6例、正确诊断率为67％．余3例中2例误诊为亚急性粟粒性播散性肺结核，1例误诊为肺内多发感染灶。结论：采用普通胸部X线片及胸部CT平扫检查，有助于进一步提高对本病的认识，减少影像的误诊及漏渗，为临床提供可靠诊断信息。

Imaging diagnosis of idiopathic pulmonary hemosiderosis

Objective:To investigate the imaging manifestations of X-ray and CT of idiopathic pulmonary hemosiderosis(IPH). Methods:9 cases of IPH confirmed by chest X-ray,CT and laboratory examination from 1998 to 2005 in our hospital were analysed retrospectively. Results:In the 9 cases confirmed by laboratory examination,only 6 cases were diagnosed as IPH in the first imaging diagnosis,the accurate rate of diagnosis was 67%;in the other 3 cases,2 cases were misdiagnosed as subacute disseminated miliary tuberculosis,one case was misdiagnosed as multiple infections foci in lung.Conclusion:Using the common chest X-ray and CT scanning will be help to improve the recognition on this disease and reduce the misdiagnosis,and provides the reliable informations to clinical diagnosis.
