title: Onyx Embolization of a Ruptured Rotundum Foreman Artery Aneurysm in a Patient with Moyamoya Disease: A Case Report.
abstract: BACKGROUND
  Hemorrhage caused by the rupture of a rotundum foreman artery pseudoaneurysm in Moyamoya disease (MMD) is rarely reported.
  
  
  METHODS
  We report a case of 46-year-old man with MMD presenting with left temporal lobe hemorrhage. Cerebral angiogram showed a pseudoaneurysm located on the rotundum branch of the left internal maxillary artery, which anastomosed with a pial vessel. Using onyx 18, we successfully embolized the pseudoaneurysm. The patient was discharged neurologically intact.
  
  
  CONCLUSIONS
  Given the difficulties and risks of surgery, onyx embolization of rotundum foreman artery aneurysm accompanied with MMD is feasible and effective.
