Tumor Thrombus of Sacral Osteosarcoma Under Inferior Vena Cava Filter.

thrombectomy was performed, and soft, white and redcolored materials that were different from typical thrombus were aspirated (Figure C). Histologically, round and spindle cells with bizarre nuclei similar to the primary myxofibrosarcoma of the sacrum were seen (Figure D). She was eventually diagnosed as having a thrombus of the sacral osteosarcoma. Thrombus arising from osteosarcoma is rare, so histological examination in this case was useful for the diagnosis.
