Malignant arrhythmia with benign tumour: fibrolipoma of the left ventricle.

We report a case of young male referred for evaluation of recent onset recurrent syncope. Inhospital electrocardiogram revealed an episode of ventricular flutter which reverted spontaneously to sinus rhythm. Transthoracic echocardiogram showed hyperechoic mass in the left ventricle. For further tissue characterization a cardiac magnetic resonance imaging was done which revealed a left ventricular mass with predominant fat content. The tumor was surgically resected. Histopathological examination confirmed the diagnosis of cardiac fibrolipoma. The patient recovered and is currently asymptomatic.
