A previously healthy 14-year-old boy with an atypically located primary cardiac osteosarcoma filling the right atrium with significant extension into both systemic and pulmonary venous structures presented with a clinical picture of heart failure. Imaging showed a large right atrial mass with posterior extension into right pulmonary veins and inferior extension into the inferior vena cava causing near total obstruction of systemic venous return to the heart. Bone marrow biopsy showed no evidence of marrow involvement by metastatic malignancy. Histopathology was a high-grade osteosarcoma. Partial tumor debulking was achieved via right atriotomy.
一名既往健康的14岁男孩，患有非典型位置的原发性心脏骨肉瘤，肿瘤充满右心房并显著延伸至体静脉和肺静脉结构，表现为心力衰竭的临床症状。影像学检查显示右心房有一个大肿块，向后延伸至右肺静脉，向下延伸至下腔静脉，导致几乎完全阻塞心脏的体静脉回流。骨髓活检未发现转移性恶性肿瘤累及骨髓的证据。组织病理学检查为高级别骨肉瘤。通过右心房切开术实现了部分肿瘤减瘤。
