title: Organised haematoma of the sphenoid sinus mimicking a pituitary tumour.
abstract: OBJECTIVE
  We report an extremely rare case of an organised haematoma arising in the sphenoid sinus.
  
  
  METHODS
  An 85-year-old woman presented with an expansile soft tissue mass in the left sphenoid sinus, with bony destruction of the sella turcica, which mimicked the extrasellar extension of a pituitary tumour. The tumour was excised using an endoscopic, transsphenoidal approach. Histopathological examination revealed an organised haematoma.
  
  
  CONCLUSIONS
  To our knowledge, this is the first report of an organised haematoma arising in the sphenoid sinus. This case indicates that organised haematoma should be included in the differential diagnosis of extensive sphenoid lesions; it also emphasises the importance of correct pre-operative diagnosis for therapeutic planning, as complete surgical resection by an endoscopic approach is curative.
