骨膜成骨肉瘤的X线诊断

骨膜成骨肉瘤（Periosteal osteogenic sarcoma）是一种很少见的恶性骨肿瘤，起源于骨外膜，发生在骨表面。1976年Unni等分析102例骨表面的成骨肉瘤，其中有23例在临床、x线和病理上不同于质旁骨肉瘤，而类似髓型成骨肉瘤，并命名为骨膜成骨肉瘤。搜集6例，均经手术病理证实，其x线表现亦颇为典型，兹报道如下。     

骨旁骨肉瘤的X线表现及其病理基础

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.
