... lds, Chest CT showed a high density linear lesion in the right truncus jntermedius. We perforrned a bronchoscopy which showed a foreign body with granuloma. Taking a detailed history revealed an episode of fish bone aspiration 20 years previously, After treatment with antibiotics, the foreign body was remeved by rigid bronchoscopy. Conclusion. Early diagnosis could avoid undetected long-standing foreign bodies which induce inflammation and granulation tissue, making them difficult to rernove, So we suggest that the possibility of an intrabronchial foreign body should be suspected in patients with a chronic cough and/or recurrentpneumoma.
