All the following X-ray findings of osteosar-coma are correct except
|A||Hazy osteolytic areas may alternate with unusually dense osteoblastic areas|
|B||The endosteal margin is poorly defined|
|C||Codman’s triangle is the reactive new bone which forms at the angle of periosteal elevation.|
|D||'Sunburst appearance' is diagnostic of osteosarcoma|
'Sunburst appearance' is diagnostic of osteosarcoma
a. In the course of growth of tumor the cortex is breached and the tumor extends into the adjacent tissues.
b. When this happens streaks of new bone appear radiating outwards from the cortex the so called 'sunburst' effect. While both sun burst appearance and Codman's triangle are typical of osteosarcoma they may be occasionally seen in other rapidly growing tumors.
