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 features of X-ray and CT imaging of idiopathic hemosiderinosis. Methods: Thoracic X-ray and CT examination were collected from 1998 to 2005. Finally, 9 cases with definite diagnosis of this disease confirmed by laboratory tests were analyzed. Results: Of the 9 cases confirmed by laboratory tests, the primary diagnosis of idiopathic hemosiderinosis was only 6 cases, the correct diagnosis rate was 67%, and 2 cases were misdiagnosed as sub-acute miliary disseminated One case of pulmonary tuberculosis was misdiagnosed as multiple intra-pulmonary infection. Conclusion: The plain chest X-ray and chest CT scan can help to further improve the understanding of the disease, reduce the misdiagnosis and missed diagnosis of the disease, and provide reliable diagnosis information for the clinic.
