title: An unusual case of empyema; intrapleural migration of an inhaled oat head in an adult.
abstract: We report an unusual case of unnoticed aspiration of an oat head by a healthy 19-year-old male. The foreign body migrated to the right pleural cavity and caused a severe persistent empyema, which resolved only after a thoracotomy . The lodging of a grass head in the pleura is a very rare event, almost never reported in an adult.
