Pulmonary aspergillomas usually occur in pre-existing lung cavities exhibiting local immunodeficiency. As pulmonary aspergillomas only partially touch the walls of the cavities containing them, they rarely come into contact with the bloodstream, which makes it difficult for antifungal agents to reach them. Although surgical treatment is the optimal strategy for curing the condition, most patients also have pulmonary complications such as tuberculosis and pulmonary fibrosis, which makes this strategy difficult. A 72-year-old male patient complained of recurrent hemoptysis and dyspnea, and a chest X-ray and CT scan demonstrated the existence of a fungus ball in a pulmonary cavity exhibiting fibrosis. Although an examination of the patient's sputum was inconclusive, his increased 1-3-beta-D-glucan level and Aspergillus galactomannan antigen index were suggestive of pulmonary aspergilloma. Since the systemic administration of voriconazole for two months followed by itraconazole for one month was ineffective and surgical treatment was not possible due to the patient's poor respiratory function, liposomal amphotericin B was transbronchially administered directly into the aspergilloma. The patient underwent fiberoptic bronchoscopy, and a yellow fungus ball was observed in the cavity connecting to the right B(2)bi-beta, a biopsy sample of which was found to contain Aspergillus fumigatus. Nine transbronchial administrations of liposomal amphotericin B were conducted using a transbronchial aspiration cytology needle, which resulted in the aspergilloma disappearing by seven and a half months after the first treatment. This strategy could be suitable for aspergilloma patients with complications because it is safe and rarely causes further complications.
肺曲菌球通常发生于已存在的肺空洞中,这些空洞表现出局部免疫缺陷。由于肺曲菌球仅部分接触包含它们的空洞壁,很少与血流接触,这使得抗真菌药物难以到达它们。虽然手术治疗是治愈该病的最佳策略,但大多数患者还伴有肺结核和肺纤维化等肺部并发症,这使得该策略难以实施。一名72岁男性患者主诉反复咯血和呼吸困难,胸部X线和CT扫描显示在一个有纤维化的肺空洞中存在一个真菌球。虽然对患者痰液的检查结果不明确,但他升高的1,3-β-D-葡聚糖水平和曲霉半乳甘露聚糖抗原指数提示肺曲菌球。由于全身应用伏立康唑两个月后接着应用伊曲康唑一个月均无效,且由于患者呼吸功能差无法进行手术治疗,因此通过支气管镜将脂质体两性霉素B直接注入曲菌球。患者接受了纤维支气管镜检查,在与右B(2)bi-β相连的空洞中观察到一个黄色真菌球,其活检样本中发现含有烟曲霉。使用经支气管吸引细胞学针进行了9次脂质体两性霉素B的经支气管给药,结果在首次治疗后7个半月曲菌球消失。该策略可能适用于有并发症的曲菌球患者,因为它安全且很少引起进一步的并发症。
