Imaging findings
An 18-year-old female presented with massive hemoptysis. Initial imaging showed a bronchocentric consolidation/filling defect in the right lower lobe bronchus with ill-defined surrounding nodules. Despite recurrent infections and lack of response to antibiotics, initial impressions of a congenital malformation with aberrant vessels were not borne out. Subsequent biopsy confirmed a mucoepidermoid tumor of the bronchus.
Key takeaways
Bronchial mucoepidermoid tumors are rare primary lung neoplasms, particularly in young patients, often misdiagnosed due to their infrequent occurrence and varied presentation. They can cause symptoms like hemoptysis and post-obstructive changes. Persistent symptoms and lack of response to conventional therapy warrant further aggressive investigation, including biopsy, to avoid delayed diagnosis. Even after successful resection, new pulmonary nodules of uncertain etiology may emerge.
