Abstract
The radiologic features of lymph node metastases from osteogenic sarcoma visible on plain films in two patients are described. In one patient the lymph node ossification was visible on presentation and in the other patient it was demonstrated six months after the initial diagnosis. The radiologic pattern in both cases was similar. Deposition of metastatic osteoid tissue in lymph nodes, to such a degree that it can be recognized on plain films, appears to be a distinctly uncommon complication of this malignant neoplasm. It is considered probable that this complication occurs with the osteoblastic type of osteogenic sarcoma. It is suggested that lymphography might be of value in the detection of such metastases at an earlier stage, thus influencing the plan of treatment
