Echocardiographic examination, performed in an asymptomatic 5 year old boy for a perimembranous ventricular septal defect (VSD), revealed a 6 x 6 mm tumor on the anterior leaflet of the mitral valve. Clinically, it was diagnosed as a benign myxoma. Histopathologic diagnosis of the excised mitral valve tumor was benign lipoma. The third case of mitral valve lipoma in the pediatric age group is reported along with a review of the literature. Echocardiogram remains the most sensitive diagnostic modality in the early detection of such neoplasms.
对一名无症状的5岁男孩进行超声心动图检查，以评估膜周部室间隔缺损（VSD），结果发现二尖瓣前叶有一个6×6毫米的肿瘤。临床上，该肿瘤被诊断为良性黏液瘤。切除的二尖瓣肿瘤的组织病理学诊断为良性脂肪瘤。本文报告了小儿年龄组二尖瓣脂肪瘤的第三例病例，并对相关文献进行了综述。超声心动图仍然是早期发现此类肿瘤最敏感的诊断方法。
