Tumour-like presentation of pulmonary sarcoidosis

Abstract

We report a case of pulmonary sarcoidosis, which initially presented as a left apical infiltrate. The later course mimicked a pulmonary neoplasm, with left upper lobe atelectasis secondary to bronchial stenosis, resulting from both endobronchial sarcoidosis and extrinsic compression by enlarged lymph nodes. Extrinsic pressure from sarcoid nodes on the left main pulmonary artery and recurrent laryngeal nerve, also caused a reduction in pulmonary parenchymal perfusion and left vocal cord paresis.
