The Comparative Study on Imaging and Pathology of the Telangiectatic Osteosarcoma / 实用放射学杂志

ABSTRACT

Objective To explore the imaging and pathological characteristics of the telangiectatic osteosarcoma.Methods The clinical,imaging and pathological data of telangiectatic osteosareoma in 12 cases were analysed.Results The tumors often located at the diaphysialepiphysial of the os longum and most of them were occured at the lower limb,increasing of the alkaline phosphatase(AKP) was rare.X-ray and CT character istics were osteoclastic and expensive bony destruction;there were multiple small cystic formation and fluid-fluid level in the destructive region and soft masess;the cortex of the bone became thinner with multiple sieve type destruction;the periosteal reaction and radial bone spicule were often seen.Pathological characteristics were of typical tumor cell of the osteosarcoma,mutliple sinus of the blood and "color bland shape" component.Conclusion The telangiectatic osteosarcoma has certain specific clinical,imaging and histologyical characteristics.
