Lipomatous Hypertrophy of the Interatrial Septum (LHIS) is a rare and benign cardiac entity that is characterized by the accumulation of adipose tissue within some segments of the interatrial septum. Patients are generally asymptomatic, and these lesions are discovered incidentally by imaging studies performed for other reasons, or in the context of an autopsy. In these patients, there have been described cases of sudden death due to disturbance of the heart rhythm. The differential diagnosis of LHIS mainly includes cardiac tumors. Here we present a case of a 61-year-old patient in whom, after a cardiac magnetic resonance study performed for an abnormal heart rhythm, it was documented a mass in the atrial septum. The patient was taken to surgery, and the histopathological study of the lesion confirmed the diagnosis. We conduct a review of the clinical and pathological characteristics of LHIS.
