RESUMO
BACKGROUND: Postpneumonectomy-like syndrome is a rare condition resulting from unilateral lung disease with severe lung volume loss leading to excessive mediastinal shift and herniation of the healthy lung into the contralateral hemithorax, mimicking the mediastinal shift observed in postpneumonectomy syndrome after pneumonectomy. We report a unique case of postpneumonectomy-like syndrome caused by an atypical bronchial carcinoid completely occluding the left main bronchus. CASE PRESENTATION: A 25-year-old woman presented with symptoms of chronic exertional dyspnea and productive cough. Imaging studies showed complete left lung atelectasis due to a mass occluding the left main bronchus, as well as extreme mediastinal deviation and substantial herniation of the right lung into the left hemithorax. Bronchoscopic biopsy of the tumor and subsequent left pneumonectomy with concurrent lymph node dissection revealed an atypical carcinoid. Sixteen months after surgery the patient has been asymptomatic with repeat imaging studies showing no change in mediastinal shifting. CONCLUSION: Bronchial carcinoids are notorious for causing bronchial obstruction. The present case represents an extreme complication of centrally located bronchial carcinoid, resulting in postpneumonectomy-like syndrome with severe mediastinal shift and herniation of the healthy lung into the diseased hemithorax.
