Rare Cardiac Angiosarcoma Detected with FDG PET/CT Imaging

Introduction

Primary cardiac tumors are among the rarest malignancies in clinical practice, and angiosarcomas top the list in terms of aggressiveness and diagnostic challenge. In a recent case study, a young patient’s life-threatening symptoms led to a surprising diagnosis: cardiac angiosarcoma with bone metastases, identified using advanced FDG PET/CT imaging.

This remarkable case emphasizes the importance of multimodal imaging in diagnosing elusive cardiac tumors. Visit https://www.cardiologymedjournal.com/jccm for more groundbreaking research in cardiovascular medicine.

When the Heart Hides a Tumor

• Patient: 26-year-old woman with non-specific symptoms like fatigue and leg swelling.
• Initial findings: Enlarged right atrium and pericardial effusion via echocardiography.
• Advanced imaging: CT and MRI uncovered a mass in the right atrium extending into nearby structures.
• Definitive scan: 18F-FDG PET/CT revealed high metabolic activity in the heart and suspicious bone lesions.

The Role of PET/CT in Revealing the Truth

The fusion of PET and CT imaging brought a clear picture of the tumor’s metabolic aggression

• SUVmax of 17.3 in the cardiac lesion
• Bone metastases confirmed in vertebrae and femurs
• No clear structural damage on CT—showing the power of metabolic imaging over morphology

Such integration supports earlier diagnosis and better treatment planning. According to the American College of Nuclear Medicine (ACNM), PET/CT imaging is invaluable for detecting elusive metastatic disease early in oncologic cases.

Histopathology and Urgent Intervention

A biopsy of the cardiac mass revealed:

• Endothelial cell malignancy
• Positive markers for CD31, CD34, vimentin, ERG, and FLI1

Bone biopsy confirmed metastatic spread. Given the disease’s advanced stage, weekly paclitaxel chemotherapy began immediately, resulting in rapid symptom relief and outpatient recovery.

Why Early Imaging Saves Lives

This case underscores how:

• Echocardiography, although essential, may miss intricate details.
• MRI and CT help visualize local infiltration.
• FDG PET/CT identifies metastatic spread invisible to conventional imaging.

According to the Radiological Society of North America (RSNA), integrating metabolic and structural imaging improves diagnostic accuracy for rare cardiac tumors.
