We present a case of primary cardiac angiosarcoma arising from the interatrial septum that had imaging features overlapping with those of right atrial myxoma. The mass was initially discovered on a thoracic CT study. Further evaluation with echocardiography was limited by poor acoustic windows and cardiac magnetic resonance (CMR) imaging was performed prior to surgical resection. CMR provided a detailed morphological assessment; imaging features included a frond-like surface architecture, a narrow attachment point at the interatrial septum, mild signal hyperintensity compared with that of myocardium on T(1) weighted sequences, patchy foci of delayed gadolinium enhancement and a haemorrhagic pericardial effusion. To the best of our knowledge, this is the first reported case of angiosarcoma arising from the interatrial septum that has undergone evaluation with CMR.
我们报告了 1 例原发于房间隔的心脏血管肉瘤病例，其影像学特征与右心房黏液瘤重叠。该肿块最初是在胸部 CT 研究中发现的。由于心脏超声检查的声窗不佳，进一步评估受到限制，随后进行了心脏磁共振（CMR）成像，然后进行了手术切除。CMR 提供了详细的形态评估；影像学特征包括叶状表面结构、在房间隔上的狭窄附着点、与 T1 加权序列相比心肌的轻度信号高信号强度、点状延迟钆增强和出血性心包积液。据我们所知，这是首例经 CMR 评估的原发于房间隔的血管肉瘤病例。
