## Abstract / Case Report

A 54-year-old woman with no medical history underwent abdominal contrast-enhanced computed tomography because of persistent epigastric pain.

The upper images discovered a large hypodense mass invading both pericardium and right atrium.

Cardiac magnetic resonance imaging confirmed a homogeneous hyperT1 and hyperT2 mass filling the right atrium, getting in contact with the tricuspid valve.

A percutaneous biopsy was obtained in order to rule out a liposarcoma. Pathologic exam confirmed a mature lipoma.

Owing to the risk of tricuspid obstruction, the patient was scheduled for semi-urgent surgical resection.

## Surgical Procedure

Under local anesthesia, the right femoral artery and vein were cannulated before general anesthesia initiation.

Cardiopulmonary bypass was initiated and a median sternotomy was performed.
The pericardium was opened and the superior vena cava was cannulated intrapericardially.

The fatty mass infiltrated the anterior wall of the right atrium, which had to be resected.

The atrial defect was replaced using a bovine pericardial patch.

## Postoperative Course

The postoperative course was uneventful.

Final pathologic report confirmed a 15.5 × 8.5 × 6 cm lipoma.
