case_images: Transthoracic echocardiogram (TTE) examination showed the following characteristics: aorta 34 mm, left atrium 35 mm, LV cavity 51 mm (end-diastolic diameter), and a hyperechoic mass 30 x 27 mm located on the left side of the heart (middle-apical region), occupying almost 2/3 of the LV with blood supply from the left anterior descending (LAD) coronary artery (Figure 1).
case_images: Computed Tomography (CT) scans. (A) CT scan showing a well-defined hypodense tumor in the left ventricle (arrow). (B) CTA 3D reconstruction; hypodense tumor (yellow arrow).

case_images: The mediastinoscope provided a more detailed view than the usual valve retractors, providing a safe resection of the mass (Figure 3).
case_images: Histopathological examination of the excised mass showed mature adipocytes, consistent with lipoma accompanied by some small vessels and limited collagenous capsule. HandE staining, x10.
