Extract
The assessment of cardiac masses is currently based on ‘Multimodality imaging’ approach.
A 53-year-old man, with a clinical history of dilated cardiomyopathy, was admitted to San Raffaele Hospital in order to remove a previous infected implantable cardioverter defibrillator (ICD)-cardiac resynchronization therapy device with ultimate exposure of the generator. At admission, no clinical or laboratory signs of endocarditis were present.
A transoesophageal long-axis view showed a homogeneous echogenic mass protruding into the right atrioventricular groove and extending to the free wall without causing inflow obstruction (Panels A and B, white arrows). After the ICD device removal, the cardiac magnetic resonance morphological cine sequences confirmed the 20 × 30 mm encapsulated and hyperintense mass in the right atrioventricular groove (Panel C, black arrows); fat-saturated images revealed the presence of fat in the mass (Panel D, white arrows), confirming the diagnosis of cardiac lipoma.
Differential diagnosis may include cardiac malignancies and iatrogenic device-related haematomas.
