Abstract
A 63-year-old male with a history of cancer, and who had undergone a left pneumonectomy seven years before, presented with deterioration in his general status and recent dyspnea [stage III (New York Heart Association) NYHA]. Imaging revealed a contralateral mediastinal shift and cardiac compression caused by pneumonectomy cavity enlargement and a retrosternal liquid mass. Late empyema associated with a retrosternal abscess caused by Propionibacterium acnes was diagnosed after thoracoscopy and an anterior mediastinotomy. Surgical treatment included an axillary open-window thoracostomy associated with negative pressure therapy (NPT), followed by a large thoracomyoplasty where part of the latissimus dorsi was harvested, and then guided healing. The chest was closed after eight months. This case is an unusual observation of a late post-pneumonectomy empyema with Propionibacterium acnes presenting like recurring cancer, but that was treated effectively using traditional (Clagett procedure) and newer (NPT) strategies.
