Neglected obstructive pneumonia: A BMJ case report
A 68-year-old man with type 2 diabetes mellitus, hypertension and history of laryngeal cancer surgery with tracheostomy was operated on in 1993 and right chest rib chondrosarcoma surgery was performed in 1997. The patient presented with fever and acute right sided hypochondrium pain. Lung examination showed decreased breath sounds over the right posterior of the lower chest.

Blood examination revealed elevation of inflammatory markers. Chest radiography showed right inferior lung lobe (RILL) consolidation and he was admitted due to community acquired pneumonia suspect.

Chest CT revealed a foreign body (FB) not visible on the chest x-ray in the inferior right stem bronchus (black arrow) complicated by an endobronchial mass (EM, black star), pleural effusion (red star) and RILL atelectasis. Neither history of FB aspiration (FBA) nor FBA-related chronic symptoms1 such as cough, haemoptysis, dyspnoea, wheeze or recurrent pneumonia were recalled by the patient.

Flexible bronchoscopy was performed and the voice prosthesis was extracted. Finally, the patient confessed that he had lost it about 1 year back.

EM biopsy revealed a granulation tissue. The patient was treated with piperacilin/tazobactam and short course of corticosteroids showing rapid improvement with significant EM size reduction.

Learning points
• Foreign body aspiration is more common in children than in adults but the diagnosis in adults is frequently overlooked.

• Although it has not been validated a short course of corticosteroids usually results in the resolution of inflammatory endobronchial mass.

• The diagnosis of foreign body airway with obstructive pneumonia is often delayed because the patients do not always report history of choking.
