[Pneumothorax Due to Formation of Pneumatocele During Treatment of Eosinophilic Pneumonia:Report of a Case].

Abstract

The patient was a 79-year-old male, During the course of treatment for eosinophilic pneumonia, he developed left-sided pneumothorax, Despite the implementation of thoracic drainage, air leakage persisted, Computed tomography(CT)revealed a left pneumatocele, which was deemed to be the underlying cause of pneumothorax, Consequently, thoracoscopy-assisted operation was performed, Six months postoperatively, no recurrence of pneumothorax was observed, and the pneumatocele had significantly decreased in size, Surgical intervention for refractory pneumothorax associated with pneumatocele is therefore considered to be an appropriate and effective therapeutic approach.
