pleural effusion

introduction

  • pleural effusion is the collection of fluid other than blood, lymph or pus between the two layers of pleura outside the lung (NB. a collection of blood is a haemothorax, a collection of lymph is a chylothorax while collection of pus is an empyema)
  • it may be mobile or loculated
  • it may be caused by transudate or an inflammatory exudate (fibrinous, serous or serofibrinous effusion which may become haemorrhagic or purulent)
  • if large it may impair respiratory function and require drainage to relieve the pressure upon the lungs
