Transthoracic 2-dimensional echocardiography detected an abnormal left atrial mass in a 71-year-old woman, which was surgically confirmed as lipomatous hypertrophy of the interatrial septum.
Case Report (n=1)
Lipomatous hypertrophy of the interatrial septum should be considered in the differential diagnosis of left atrial masses detected via echocardiography, especially in elderly and obese patients.
A 71-year-old woman underwent echocardiography for the evaluation of hypertensive heart disease. A 2-dimensional echocardiogram revealed an abnormal mass that protruded into the left atrium from the atrial septal side of the left atrial wall. Microscopic examination of the surgical specimen disclosed a mixture of normal-appearing fat, vesicular fat, and hypertrophied myocytes, and degenerated cardiac tissue with foci of necrotic fat tissue, consistent with lipomatous hypertrophy. Although lipomatous hypertrophy of the interatrial septum is rare, this little-known entity should be included in the differential consideration of the left atrial mass detected via echocardiographic examination, particularly in both obese and elderly patients.
Nobuoka et al. (Sun,) conducted a case report in Lipomatous hypertrophy of the interatrial septum (n=1). Transthoracic 2-dimensional echocardiography was evaluated on Detection and microscopic confirmation of lipomatous hypertrophy. Transthoracic 2-dimensional echocardiography detected an abnormal left atrial mass in a 71-year-old woman, which was surgically confirmed as lipomatous hypertrophy of the interatrial septum.
