Abstract/OtherAbstract:
A young man presented with recurrent ischemic stroke under antiplatelet therapy. A patent foramen ovale (PFO) was diagnosed by transesophageal echocardiography (TEE) and the patient was referred to our institution for percutaneous closure. An echogenic mass in the right atrium was detected during the intraprocedural TEE. The interventional team decided to perform transcatheter closure of PFO under fluoroscopy and TEE guide, without complications. Subsequent cardiac magnetic resonance (CMR) imaging confirmed an encapsulated and hyperintense mass located in the roof of the right atrium. The signal intensity pattern and the absence of gadolinium contrast uptake allowed a confident diagnosis of lipoma. Cardiac lipoma accounts for about 10% of primary cardiac tumors and frequently rises from the epicardial fat tissue. Echocardiographic images can remain equivocal about the nature of the mass and CMR offers a substantial contribution to a correct diagnosis. The tumor usually appears encapsulated and asymptomatic, but dyspnea, atrial and ventricular arrhythmias and, rarely, peripheral embolization have been reported. To our knowledge, this is the second case reported on paradoxical embolization associated with right atrial lipoma. Although the relationship of cardiac lipoma with stroke is not well defined, the potential proembolic significance of this lesion cannot be excluded, especially when a PFO coexists.
