Silent Invader: A Rare Right Ventricular Lipoma Resolved With Multimodal Imaging

Area of Science:

• Cardiology
• Oncology
• Radiology

Background:

• Incidental diagnosis of cardiac masses can pose challenges in clinical practice.
• Bilateral thyroid cancer patients require comprehensive health monitoring.
• Right ventricular masses necessitate accurate diagnostic evaluation.

Observation:

• A 36-year-old female with bilateral thyroid cancer presented with an incidentally discovered 5.6x4.3 cm right ventricular mass.
• Initial echocardiography (TTE) and cardiac CT suggested a fat-density lesion.
• The mass was further characterized using multimodal imaging, including Myocardial Contrast Echocardiography (MCE), CT, and Cardiac Magnetic Resonance (CMR).

Findings:

• Multimodal imaging confirmed the right ventricular mass as a cardiac lipoma, a rare benign tumor.
• The diagnostic process precisely delineated the tumor's size, characteristics, and impact on cardiac function.
• Surgical planning was effectively guided by the comprehensive imaging data, leading to successful tumor resection.

Implications:

• This case underscores the indispensable role of multimodal imaging in diagnosing and managing rare cardiac tumors.
• Accurate diagnosis and timely intervention are crucial for favorable patient outcomes.
• Integrating advanced imaging techniques improves the characterization and treatment strategies for cardiac lipomas.
