On transthoracic echocardiogram (Figure 1), a large homogenously hyper echoic lesion was seen in the interventricular septum.
Cardiac computed tomography, axial image, hypodense lesion of -90 HU (fat) noted in the interventricular septum (black arrow).

The non contrast Cardiac CT (Figure 2) confirmed the presence of a solid infiltrative lesion with fat density (-90 HU) in the interventricular septum, confirming its lipomatous origin.
Cardiac magnetic resonance imaging, axial T1 weighted image, shows hyperintense lesion (black arrow) in the interventricular septum.

T1 (Figure 3) and T2 weighted sequences, with a complete suppression of the signal on fat suppression sequence (STIR, Figure 4), confirming it to be a fat containing mass. The lesion did not cause ventricular compression or obstruction to left ventricular outflow tract.
Cardiac magnetic resonance imaging, axial fat suppression STIR sequence, shows complete signal suppression of the interventricular septal lesion (white arrow).
