A 60-year-old man with a history of benign prostate hyperplasia was referred to our clinic for evaluation of persistent left lower lobe chest X-ray (CXR) changes and symptoms suggestive of recurrent chest infection that did not improve with antibiotic therapy. On history, the patient vividly recalled an episode of violent coughing 3 months ago while eating peanuts. Thereafter, he reported daily cough with clear productive sputum and breathlessness on heavy exertion. The patient is a lifelong non-smoker and reported no other infective or cardiac symptoms, or relevant environmental exposures. On examination, the patient was not dyspnoeic. Temperature was 37.2°C, respiratory rate 12 breaths/min and room air oxygen saturation 97%. Chest auscultation revealed left basal coarse crackles which did not clear on coughing. The remainder of the clinical examination was normal.
