Abstract
A 68-year-old woman who was urgently taken to her previous hospital because of right back pain and dyspnea, but was transferred to our hospital owing to the absence of a specialist. Chest computed tomography revealed a lung abscess in the right middle lobe and a multiloculated (approximately 3 sites) pyothorax. Blood biochemistry tests indicated the presence of a severe inflammatory reaction and untreated Type 2 diabetes mellitus. Upon admission, a trocar catheter was inserted due to the multiloculated pyothorax; aspiration kits were inserted on postadmission Days 3 and 4. Intrapleural lavage with urokinase was performed from the trocar catheter for 5 days. Another aspiration kit was inserted on postadmission Day 19 due to the pneumothorax caused by the perforation of the lung abscess. The air leakage was stopped on postadmission Day 26. Antimicrobial therapy, drainage, and urokinase instillation alleviated her symptoms, and she was discharged on postadmission Day 43.
