Abstract

Introduction

Legionella pneumonia can appear with different levels of severity and it can often present with complications such as acute respiratory distress syndrome.

Case presentation

We report the case of a 44-year-old Caucasian man with Legionella pneumonia with successive development of severe acute respiratory distress syndrome. During his stay in intensive care the clinical and radiological situation of the previously observed acute respiratory distress syndrome unexpectedly worsened due to acute pulmonary eosinophilic infiltrate of iatrogenic origin.

Conclusion

Levofloxacin treatment caused the occurrence of acute eosinophilic infiltrate. Diagnosis was possible following bronchoscopic examination using bronchoaspirate and transbronchial biopsy.
