We report the noninvasive imaging diagnosis of a massive right atrial lipoma in a young male patient. Echocardiography and myocardial contrast echocardiography were used to assess echo intensity, tumor size, anatomic boundary, hemodynamics, and contrast agent perfusion. Dual-source CT revealed that the CT value of the tumor was fat density. Cardiac MRI showed high signals of T1 and T2 weighted images, while the low signals of fat saturation sequences. Finally, the tumor was surgically resected and the diagnosis of right atrial lipoma was confirmed by pathological section. Our study indicates that multimodal imaging may facilitate a potential pathological diagnosis before biopsy and can help plan further treatment.
我们报告了一名年轻男性患者巨大右心房脂肪瘤的无创成像诊断。使用超声心动图和心肌对比超声心动图评估回声强度、肿瘤大小、解剖边界、血流动力学和造影剂灌注。双源CT显示肿瘤的CT值为脂肪密度。心脏MRI显示T1加权像和T2加权像呈高信号，而脂肪饱和序列呈低信号。最后，手术切除肿瘤，病理切片证实为右心房脂肪瘤。我们的研究表明，多模态成像可能有助于在活检前进行潜在的病理诊断，并有助于规划进一步的治疗。
