Key result
Lipomatous atrial hypertrophy can progressively involve the RA wall, mimicking intracavitary masses on echo.
Case Report (n=2)
Lipomatous atrial hypertrophy can involve the right atrial wall and progress over time, mimicking intracavitary masses on echocardiography.
May mimic right atrial masses on echocardiography; leaves open optimal imaging strategies for confirmation.
Lipomatous atrial hypertrophy is a generally benign abnormality characterized by the deposition of adipose tissue in the interatrial septum and is usually detected as an incidental echocardiographic finding. We present two cases in which the presence of lipomatous atrial hypertrophy was diagnosed by transthoracic echocardiography, but tangential cuts of a more diffuse lipomatous process suggested the presence of intracavitary right atrial mass lesions. Transesophageal echocardiography provided additional details of significant right atrial wall involvement. In one case computer assisted tomographic scans showed a progression of thickening over a 4-year period. Lipomatous atrial hypertrophy can be a more generalized and progressive abnormality then previously thought and should be considered in the differential diagnosis of echocardiographic intracavitary right atrial masses.

Cohen et al. (1993) conducted a case report in Lipomatous atrial hypertrophy (n=2). Lipomatous atrial hypertrophy was evaluated. Lipomatous atrial hypertrophy can present as a generalized and progressive abnormality involving the right atrial wall, mimicking intracavitary right atrial masses on echocardiography.
