A Giant Cardiac Lipoma Associated With Ventricular Inversion and Ventricular Aneurysm: Ultrasonography and CT Imaging Findings

Cardiac lipomas are rare, mostly asymptomatic, and usually found incidentally during noncardiac examinations; however, they also can be symptomatic, depending on their size and location. Here, we report a case of surgically proved pericardial lipoma that was big and for which cardiac structures were substantially altered. The combination of CT imaging and ultrasonography enabled a precise diagnosis in terms of localization, tissue characterization, and complications of the tumor. The origin of the tumor, however, remains undetermined despite a series of postoperative CT scan and ultrasound examinations.
