Invasive aspergillosis is a serious complication in immunocompromised patients. It is an opportunistic disease, which predominantly occurs in the lungs, although dissemination to virtually any organ is possible. Invasive aspergillosis in an immunocompetent patient with extension to the mediastinum has rarely been reported. Here, we present the case of a patient with no apparent immunodeficiency state, who presented with Aspergillus endocarditis and fulminant invasive aspergillosis with extensive involvement of the mediastinal structures, which ultimately was responsible for her death. To the best of our knowledge, this is the first reported case in the literature on fulminant invasive mediastinal aspergillosis with extension to the pulmonary vasculature and concomitant Aspergillus endocarditis in an apparently immunocompetent patient without pre-existing lung disease.
Our patient was a previously healthy 47-year-old Asian woman, who presented to our emergency room with severe progressive shortness of breath of one month's duration, associated with orthopnea and unstable vital signs.
Invasive aspergillosis has been described in the presence of pulmonary disease, such as chronic obstructive pulmonary disorder, and one case has been reported in a patient without preexistent disease, but none of these have been fatal. Our case is therefore the first reported case of its kind. Our case shows that fulminant aspergillosis can occur in an immunocompetent host and can be fatal. We conclude that invasive aspergillosis should not be excluded from the differential diagnosis on the basis of immunocompetency.
侵袭性曲霉病是免疫功能低下患者的一种严重并发症。它是一种机会性疾病,主要发生在肺部,尽管几乎可播散至任何器官。免疫功能正常的患者发生侵袭性曲霉病并累及纵隔的情况鲜有报道。在此,我们报告一例无明显免疫缺陷状态的患者,该患者出现曲霉菌性心内膜炎和暴发性侵袭性曲霉病,纵隔结构广泛受累,最终导致其死亡。据我们所知,这是文献中首次报道的一例明显免疫功能正常且无既往肺部疾病的患者发生暴发性侵袭性纵隔曲霉病并累及肺血管及合并曲霉菌性心内膜炎的病例。
我们的患者是一名47岁的既往健康的亚洲女性,因持续一个月的严重进行性气短、伴有端坐呼吸和生命体征不稳定而就诊于我们的急诊室。
侵袭性曲霉病已在存在肺部疾病(如慢性阻塞性肺疾病)的情况下被描述,并且有一例报道是在无既往疾病的患者中发生,但这些均未致命。因此我们的病例是此类报道中的首例。我们的病例表明暴发性曲霉病可发生在免疫功能正常的宿主中且可能致命。我们得出结论,不应基于免疫功能正常而将侵袭性曲霉病排除在鉴别诊断之外。
