title: [Giant cavernous sinus haemangioma. Case report].
abstract: BACKGROUND
  Intracranial haemangioma is a benign vascular tumor which seldom affects the cavernous sinus region, being it frequently misdiagnosed as a meningioma.
  
  
  METHODS
  A 60-year-old woman presented with a subacute-onset third cranial nerve palsy. A giant extraaxial mass located in the middle cranial fossa which extended into the selar and supraselar areas was diagnosed. It showed homogeneous enhancement after contrast administration. The angiography revealed mild enhancement as well as indirect signs of mass effect, and a tumoral embolization was performed. Surgery and outcome. The tumor was partially removed through a left pterional approach, leaving an intraselar remnant. The patient had an uneventful postoperative course, and did not present new neurological deficits.
  
  
  CONCLUSIONS
  The haemangioma must be considered in the differential diagnosis of cavernous sinus tumours. This entity represents a neurosurgical challenge, due to the complexity of this anatomical region and the trend of the tumour to bleed during its dissection.
