  • Title: [The roentgen findings and pathological basis of parosteal osteosarcoma].
    Author: Duan CX.
    Journal: Zhonghua Fang She Xue Za Zhi; 1989 Jun; 23(3):157-60. PubMed ID: 2582907.
    Abstract:
    The roentgen findings of 17 cases of parosteal osteosarcoma were analyzed. In 13 of them, a patho-radiologic correlative study was conducted. The results showed that there was an obvious relationship between the radiologic pattern and the degree of malignancy. On roentgenogram, tumor with dense ivory bone as the main manifestation is mostly lower in malignancy, while cotton-like and spiculate tumor bone usually denotes higher degree of malignancy. The pathological basis of the radiolucent area inside the tumor, the satellite nodules in the vicinity of the tumor as well as the differential diagnosis were discussed.
