Trust in the patient's history: cough and eels

A 54-year-old ex-smoker was referred to the respiratory clinic for breathlessness and wheeze. His symptoms started while eating jellied eels when he felt something stick in his throat. The following day, his general practitioner heard a wheeze in his right lower chest. A chest radiograph noted no foreign body. A course of antibiotics did not help, but steroids were beneficial. On clinic review the examination was normal apart from enlarged and inflamed tonsils. Fibreoptic bronchoscopy revealed a suspicious looking mass lesion completely occluding the bronchus intermedius. Biopsies of the lesion revealed inflamed bronchial mucosa and a fragment of bone. There was no evidence of dysplasia or malignancy. A computed tomography scan of the thorax revealed a 5 mm endobronchial soft tissue density with areas of calcification within the bronchus intermedius. At rigid bronchoscopy a spiny bone was removed and subsequently the patient's shortness of breath, cough and wheeze improved.
