"Telangiectatic osteosarcomas make up for 2-12% of high-grade osteosarcomas with varying frequencies between studies 1-6. They have similar demographics to that of conventional osteosarcoma and typically occur in adolescents and young adults 4,5 (reported age range of 3-67 years ref with a median age of 15- 20 years 5). There is a recognised male preference 4,5."

"aneurysmal bone cyst (ABC): should not have any soft tissue component outside the lesion and will have a narrower transitional zone. Smooth septal and rim enhancement is seen without nodularity, osteoid matrix mineralisation or aggressive features like cortical destruction and infiltration into surrounding tissue (unlike telangiectatic osteosarcoma) 11"

"The femoral, humeral and tibial diaphyseal regions as well as the pelvic bones are less common with frequencies ranging from ~5-7% for the mid-femur to ~3% in the pelvis 5."
"Rare locations are the fibula, skull and ribs with a frequency"
