We report a 64-year-old man with ossifying cardiac myxoma which radiographically demonstrated visible calcification. A lateral chest radiograph showed abnormal calcification in the cardiac shadow. Two-dimensional and transesophageal echocardiography revealed a heterogeneous mass with a hyperechoic lesion in the left artium. A coronary angiogram showed a neovascular formation extending from the coronary arteries to the tumor. The resected tumor was composed of round or spindle shaped cells with myxoid stroma, accompanied by extensive calcification and ossification containing fatty and hematopoietic marrow tissue. Although a left atrial calcified myxoma is less common than a right sided myxoma, and such radiographically detectable calcified tumors are rare, the presence of radiographic visualized calcification in the cardiac shadow should be ruled out for left as well as right atrial myxomas.
我们报告了一名64岁患有骨化性心脏黏液瘤的男性患者,影像学检查显示可见钙化。胸部侧位X线片显示心脏阴影中有异常钙化。二维和经食管超声心动图显示左心房内有一个不均质肿块,伴有高回声病变。冠状动脉造影显示有新血管形成,从冠状动脉延伸至肿瘤。切除的肿瘤由圆形或梭形细胞组成,伴有黏液样基质,同时有广泛的钙化和骨化,包含脂肪和造血骨髓组织。虽然左心房钙化黏液瘤比右心房黏液瘤少见,且这种在影像学上可检测到的钙化肿瘤罕见,但对于左、右心房黏液瘤,均应排除心脏阴影中影像学可见钙化的存在。
