Issues and Technologies in Level Boarding Strategies for BRT

Abstract

Osteosarcoma is one of the most common primary malignant bone tumors in children and adolescents. Telangiectatic osteosarcoma is an unusual variant of osteosarcoma, forming 3% to 10% of all osteosarcomas. Radiographically, these tumors appear as purely lytic destructive lesions located in the metaphyses of long bones. The location and x-ray appearance of telangiectatic osteosarcomas are reminiscent of an aneurysmal bone cyst and can test the acumen of a diagnostic radiologist. Distinguishing between the two entities microscopically can also be quite challenging. Telangiectatic osteosarcoma shows dilated blood-filled spaces lined or traversed by septa containing atypical stromal cells, with or without production of a lacelike osteoid matrix. This review highlights the diagnostic features of telangiectatic osteosarcoma and discusses differential diagnostic considerations, treatment options, and prognostic implications.
