Contralateral Pneumothorax Mimicking Bilateral Pneumothoraces in a Patient with Autopneumonectomy

Abstract

Contralateral pneumothorax crossing the midline in a patient with autopneumonectomy can mimic bilateral pneumothoraces on chest radiography. In this study, we report a rare case of right pneumothorax mimicking bilateral pneumothoraces in a patient with left autopneumonectomy. A 37-year-old man complained of progressive chest pain and dyspnea. The initial chest radiography revealed visible visceral pleura with air in bilateral upper pleural spaces, suggesting bilateral pneumothoraces. Mediastinal structures were shifted to the left side and increased opacities with internal tubular and cystic radiolucencies were noted in the left lower lung zone. After immediate placement of a drainage tube into the right pleural space, the patient underwent chest computed tomography (CT). CT scan revealed a destroyed and totally collapsed left lung and hyper-inflated right lung with right pneumothorax crossing the midline. The contralateral pneumothorax was then gradually absorbed by keeping the chest tube in the right hemithorax. No pneumothorax recurred in 2 years of follow-up. A greater awareness of this rare condition is important in clinical practice, as catastrophic consequences can occur if a chest tube is blindly placed in the autopneumonectomy site.
