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.
