Cardiac Lipoma: An Uncharacteristically Large Intra-Atrial Mass Causing Symptoms

Abstract EN

Primary tumours of the heart are often encountered in clinical practice.

Different autopsy series estimate the incidence to be anywhere from 0.001% to 0.19%.

Cardiac lipoma is a rare type of tumour of the heart and pericardium.

It comprises approximately 10–19% of all cardiac tumours.

We present a case of a large cardiac lipoma in a fifty-year-old female.

She presented with sharp chest pains, palpitations, and dizziness.

Acute coronary syndrome was ruled out.

A transthoracic echocardiogram showed an abnormal, large, fixed right atrial mass.

The mass was noted to be occupying most of the right atrium.

It was excised due to its large size and persistent symptoms.

On pathophysiology, the mass was definitively diagnosed to be an 80 mm × 70 mm cardiac lipoma.

Postoperatively, the patient did well with resolution of her symptoms.

This case provides evidence that even large, invasive, symptomatic cardiac lipomas can be successfully resected with good outcomes.
