Aspirated Almond Masquerading as an Obstructing Endobronchial Mass Suspicious for Lung Cancer

Foreign body aspiration is relatively rare in adults compared to children. In adults with delayed presentation, a history of choking is often absent, resulting in delayed diagnosis and significant morbidity. Common presenting features in adults include nonresolving cough with or without fever, hemoptysis, or wheezing and may mimic infectious, inflammatory, or neoplastic disorders. We present a case of a 64-year-old man with 80-pack-year smoking history who had a nonresolving left lower lobe infiltrate on chest radiograph after treatment for community-acquired pneumonia. His insidious-onset symptoms included cough, decreased exercise tolerance, and localized wheezing. Computed tomography of the chest showed a left lower lobe consolidation, with narrowing of the bronchus. Flexible bronchoscopy revealed a fleshy endobronchial mass, prompting endobronchial needle aspiration and biopsies, all of which revealed acute inflammation on rapid onsite evaluation. After multiple biopsies, a white pearly object with a detached brown cover was revealed; the object was found to be an aspirated almond. The almond and its peel were retrieved. The patient acknowledged that he had frequently eaten almonds in the supine position while recovering from a previous injury. His symptoms completely resolved at 3-month follow up, and he has ceased smoking and no longer consumes food while supine.
