Abstract
A 55-year-old man presented with a 2-week history of cough, expectoration, and transient hemoptysis. Contrast-enhanced CT revealed a mildly heterogeneous soft-tissue nodule in the left upper bronchus, causing distal obstructive atelectasis. Bronchoscopy identified an endoluminal tumor at the left upper lobe orifice; initial biopsy suggested adenoid cystic carcinoma. Staging 18 F-FDG PET/CT demonstrated increased FDG activity in the nodule with no evidence of metastatic disease. Following surgical resection, histopathology confirmed a salivary gland-type tumor: intermediate-grade mucoepidermoid carcinoma. The patient recovered well postoperatively.
