A 40 year-old athletic woman presented with worsening dyspnea on exertion over the preceding several months. Chest radiograph showed borderline cardiomegaly and subsequent echocardiography demonstrated a 5.0-cm left atrial mass as well as left-to-right interatrial shunting through a patent foramen ovale. Cardiac magnetic resonance imaging was performed, which demonstrated signal characteristics consistent with an atrial myxoma. The patient then underwent urgent surgical treatment with good technical and clinical outcome. Histologic examination confirmed an atrial myxoma. Cardiac magnetic resonance imaging was valuable in characterizing the nature of the atrial mass and patent foramen ovale, helping guide the surgical approach.
一名40岁的运动型女性在过去几个月中出现运动时呼吸困难加重的症状。胸部X光片显示心脏轻度增大，随后的超声心动图显示左心房有一个5.0厘米的肿块，以及通过卵圆孔未闭的左向右心房分流。进行了心脏磁共振成像，其显示的信号特征与心房黏液瘤一致。该患者随后接受了紧急手术治疗，手术技术和临床效果良好。组织学检查证实为心房黏液瘤。心脏磁共振成像在确定心房肿块和卵圆孔未闭的性质方面很有价值，有助于指导手术方法。
