What is Lipomatous Hypertrophy of the Interatrial Septum Is a Pathologic, Not an Anatomic Diagnosis about?

## Background and aim: Lipomatous hypertrophy of the interatrial septum (lhis), a fatty tumor, is usually diagnosed on both echo and ct/mri imaging. cases of lhis located outside of the interatrial septum are extremely rare and rarer still are these cases large enough to cause symptoms. the clinical literature demonstrates a misunderstanding that fatty tumors outside the intra-atrial area represent lipomas. however, pathologic understanding of these fatty tumors is clear and is based on microscopic findings. ## Methods: The tumor was removed by diving the base of attachment at the left ventricular apex via a median sternotomy on cardiopulmonary bypass. ## Results: The patient made an uneventful recovery and remains well at 6 months postoperatively. ## Conclusions: On rare occasions, lhis can arise from outside the interatrial septum. an lhis can be differentiated from a lipoma by the presence of entrapped cardiac myocytes in lhis, making it a pathological, rather than an anatomic, diagnosis.
