We present a case of a 50-year-old female evaluated for a 1-year history of numbness of the first and second toe of the right foot. Echocardiography performed in order to exclude cardiovascular compromise revealed a granular mass originating from the posterior part of the interatrial septum. On subsequent magnetic resonance imaging (MRI) with fat suppression sequences, the final diagnosis of lipomatous hypertrophy of the interatrial septum, a benign and underrecognized condition characterized by septal accumulation of fatty tissue, was made. Although no previous reports have focused on this, tailored cardiac MR with fat suppression sequences proved to be an excellent noninvasive method in assessing an accurate diagnosis and in differentiating lipomatous hypertrophy of the atrial septum from other cardiac neoplasms.
我们报告一例50岁女性，因右脚第一和第二趾麻木1年前来评估。为排除心血管功能受损而进行的超声心动图检查发现，一个颗粒状肿块起源于房间隔后部。随后，在采用脂肪抑制序列的磁共振成像（MRI）检查中，最终诊断为房间隔脂肪瘤样肥大，这是一种良性且未得到充分认识的疾病，其特征为脂肪组织在房间隔积聚。尽管此前尚无相关报道，但事实证明，采用脂肪抑制序列的定制心脏磁共振成像在准确诊断以及区分房间隔脂肪瘤样肥大与其他心脏肿瘤方面是一种出色的非侵入性方法。
