Osteogenic sarcoma is an aggressive malignant bone tumor arising from primitive mesenchymal bone-forming cells. Ossification is the characteristic feature of the metastases in osteosarcoma which aids their detection on Tc-MDP bone scintigraphy. Although lung is the most common site of metastasis in osteogenic sarcoma, pleural involvement with effusion and skip metastases are rare. Herein, we report a case of osteogenic sarcoma of distal femur with diffuse calcified pleural thickening leading to malignant pleural effusion, calcified lung, lymph node, and bone metastases illustrated on bone scan.
骨肉瘤是一种起源于原始间充质骨形成细胞的侵袭性恶性骨肿瘤。骨化是骨肉瘤转移灶的特征性表现，有助于在锝-亚甲基二膦酸盐（Tc-MDP）骨闪烁显像上检测到它们。虽然肺是骨肉瘤最常见的转移部位，但伴有胸腔积液的胸膜受累及跳跃转移很少见。在此，我们报告一例股骨远端骨肉瘤病例，其表现为弥漫性钙化性胸膜增厚导致恶性胸腔积液，骨扫描显示有钙化的肺部、淋巴结及骨转移。
