title: Cavernous Angioma of the Cerebral Aqueduct.
abstract: BACKGROUND
  Among the rare intraventricular cavernomas, purely intra-aqueductal cavernomas are exceptionally rare.
  
  
  METHODS
  A 62-year-old patient presented with progressive headache, memory loss, gait instability, and urinary incontinence. Magnetic resonance imaging showed the presence of a mass lesion located in the lumen of the cerebral aqueduct, associated with triventricular hydrocephalus.
  
  
  CONCLUSIONS
  We discuss the rationale that led us to treat hydrocephalus with neuroendoscopy, which offered the possibility to directly inspect the intra-aqueductal lesion, make the diagnosis of cavernoma, and treat symptoms resulting from hydrocephalus without increasing the risk of bleeding.
