Abstract:
Aneurysmatic bone cysts are benign lesions of unknown origin. It has been postulated that they might occur in reaction to trauma or to a primary benign (giant cell tumor, chondroblastoma, etc.) or malignant (osteosarcoma) bone tumor that results in local hemodynamic changes. Their malignant transformation is controversial. We present a case of low grade osteosarcoma with a radiologic progression that was indistinguishable from that of an aneurysmatic bone cyst.
