Aneurysmal bone cyst

Aneurysmal bone cyst

  • It is a rare, localized, non-neoplastic, proliferative lesion of vascular tissue, containing giant cells.
  • It usually occurs in young patients.
  • Most common location: molar and ramus of the mandible.
  • Small early lesion may be unilocular but as the lesion grows it becomes multilocular (soap bubble or honeycomb appearance).
  • Often well defined and well corticated borders.
  • It may cause marked bony expansion and displacement of the adjacent teeth (resorption is rare).
