在计算机断层扫描上,COVID-19肺炎可能与耶氏肺孢子虫肺炎(PJP)混淆,这是误诊的一个来源。这可能导致虐待和死亡风险增加。吉非替尼是一种酪氨酸激酶抑制剂,用于肿瘤治疗和糖皮质激素治疗,可增加PJP的风险。一名82岁的妇女因晚期肺癌接受吉非替尼治疗,因呼吸困难被急诊科收治。胸部计算机断层扫描发现异常,归类为可能的弥漫性COVID-19肺炎。SARS冠状病毒2型RT-PCR检测结果为2次阴性。支气管肺泡灌洗肺孢子虫PCR阳性。最终诊断为耶氏肺孢子虫肺炎。因此,医生必须小心不要误诊COVID-19,特别是在使用吉非替尼和皮质类固醇等小分子治疗药物的癌症患者中。
COVID-19 pneumonia can be confused with Pneumocystis jirovecii pneumonia (PJP) on computed tomography and is a source of misdiagnosis. This can lead to mistreatment and an increased risk of mortality. Gefitinib, a tyrosine kinase inhibitor anti-EGFR used in cancer therapy and corticosteroids, could increase the risk of PJP. An 82-year-old woman treated for advanced lung cancer with gefitinb was admitted to the emergency unit complaining of dyspnea. Chest computed tomography found abnormalities classified as possible diffuse COVID-19 pneumonia. RT-PCR for Sars-Cov-2 was twice negative. PCR for Pneumocystis jirovecii was positive on bronchoalveolar lavage. The final diagnosis was Pneumocystis jirovecii pneumonia. Therefore, physicians must be careful not to misdiagnose COVID-19, especially in cancer patients on small-molecule therapeutics like gefitinib and corticosteroids.
