Abstract：
BACKGROUND: Pulmonary cavities caused by Legionella occur mainly in immunocompromised patients, and clinical information in patients with normal immune function is therefore limited.
METHODS: We report a 64-year-old female who developed a Legionella pulmonary cavity without any immunological abnormality.
RESULTS: She suffered severe pneumonia complicated by acute respiratory failure and acute renal insufficiency. Despite long-term antibiotic therapy, she showed signs of a life-threatening infection and a progressive pulmonary cavity.
CONCLUSIONS: Our case report provided clinical data regarding the diagnosis and therapy of patients who develop Legionella pulmonary cavities without any underlying disease.

摘要：
背景：军团菌引起的肺腔主要发生在免疫功能低下的患者中，因此，免疫功能正常的患者的临床信息有限。
方法：我们报告了一名64岁的女性，她出现了军团菌肺腔，没有任何免疫异常。
结果：她患有严重的肺炎，并发急性呼吸衰竭和急性肾功能不全。尽管有长期的抗生素治疗,她表现出危及生命的感染和进行性肺腔的迹象。
结论：我们的病例报告提供了没有任何基础疾病的军团菌肺腔的诊断和治疗的临床数据。
