Inhalation of a food foreign body is a rare phenomenon in adults, it can be serious and life-threatening. We report the observation of a 37-year-old patient with chronic bronchitis for 10 years, without notion of ingestion of an obvious digestive foreign body but who presents a progressive worsening of her bronchorrhea becoming purulent associated with a single episode of hemoptysis of low abundance. Chest radiography revealed an alveolar type opacity with left paracardiac projection. The chest CT scan showed dilatation of the bronchi downstream of a lesion at the left lower lobar level. The flexible bronchoscopy showed a foreign body which is a sunflower seed obstructing the orifice of the left lower lobar bronchus with notion of regular consumption of Sunflower seeds for 20 years later found during interrogation. The extraction of the foreign body was carried out surgically or a lower lobectomy was carried out in connection with the failure of the endoscopic extraction and the patient benefited from antibiotic therapy and respiratory physiotherapy, as well as awareness raising in order to avoid subsequent penetration syndrome. The development was very favorable. Intrabronchial foreign bodies after failure of their extraction by bronchial endoscopy.
