Aneurysmal Bone Cyst
Reactive bone formation may be seen in the larger septa of aneurysmal bone cysts. Prominent osteoblastic activity is seen along anastomosing bony trabeculae in this image. The treatment of aneurysmal bone cyst is complete surgical excision of the lesion. Sometimes, the lesion regresses even after incomplete removal. Prognosis is excellent and recurrences are rare.
