case_images: A 16 year old girl, asymptomatic with lipomatous hypertrophy of the interventricular septum. Transthoracic echocardiogram showing a large homogenously hyperechoic lesion (black arrow) in the interventricular septum.

case_images: fig1-11795476211024848
case_images: On transthoracic echocardiogram (Figure 1), a large homogenously hyper echoic lesion was seen in the interventricular septum.
case_images: Cardiac computed tomography, axial image, hypodense lesion of -90 HU (fat) noted in the interventricular septum (black arrow).

case_images: fig2-11795476211024848
case_images: 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.
case_images: Cardiac magnetic resonance imaging, axial T1 weighted image, shows hyperintense lesion (black arrow) in the interventricular septum.

case_images: fig3-11795476211024848
case_images: 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.
case_images: Cardiac magnetic resonance imaging, axial fat suppression STIR sequence, shows complete signal suppression of the interventricular septal lesion (white arrow).
