特发性含铁血黄素沉着症影像诊断分析

Imaging diagnosis of idiopathic pulmonary hemosiderosis

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检查,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诊,为临床提供可靠诊断信息。

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 tube,,culosis, one case was misdiagnosed as multiple infections foci in lung.Concision：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.
