Abstract:
A 61-year-old female presented with right atrial mass during physical examination. Contrast-enhanced left heart echocardiography revealed a mass with the size of 32*23 mm in the right atrium, attached to the atrial septum; there was a certain degree of activity and deformation. MRI showed a mass of about 35*22 mm in the right atrium adjacent to the atrial septum, which was diagnosed with right atrial myxoma. Intraoperative TEE showed that the mass was located in the atrial septum close to the inferior vena cava and spontaneous echo contrast with hyperechoic images within the mass. The lesion was resected under cardiopulmonary bypass. Pathological examination revealed that the filling defect was an atrial septal hematogenous cyst with calcification.
摘要:
一名61岁女性在体检中出现右心房肿块。左心超声造影显示右心房有一块32*23mm大小的肿块,附着在房间隔上;有一定程度的活动和变形。MRI显示右心房邻近房间隔约35*22毫米的肿块,被诊断为右心房粘液瘤。术中TEE显示肿块位于靠近下腔静脉的房间隔中,自发回声与肿块内的高回声图像形成对比。在体外循环下切除病灶。病理检查显示充盈缺损为房间隔血源性囊肿伴钙化。
