%X <B>BACKGROUND: </B>Pulmonary cavities caused by Legionella occur mainly in immunocompromised patients, and clinical information in patients with normal immune function is therefore limited.<BR><B>METHODS: </B>We report a 64-year-old female who developed a Legionella pulmonary cavity without any immunological abnormality.<BR><B>RESULTS: </B>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.<BR><B>CONCLUSIONS: </B>Our case report provided clinical data regarding the diagnosis and therapy of patients who develop Legionella pulmonary cavities without any underlying disease.
