Summary
Hepatocellular carcinoma rarely metastasizes to the heart. This case highlights the importance of considering cardiac metastasis in patients with a history of liver cancer, especially when symptoms arise after treatment.
Area of Science:
- Cardiology
- Oncology
- Hepatology
Background:
- Hepatocellular carcinoma (HCC) is a primary liver malignancy.
- Cardiac metastasis from HCC is exceptionally rare.
- Patients with a history of HCC require comprehensive follow-up.
Observation:
- A 49-year-old female with a history of liver resection for HCC presented with a cardiac tumor.
- The tumor was identified as obstructing the right ventricular outflow tract.
- The patient underwent two surgical procedures with cardiopulmonary bypass.
Findings:
- Surgical intervention successfully relieved the patient's symptoms.
- The cardiac tumor was confirmed to be a metastasis from the primary liver cancer.
- This case underscores the potential for HCC to spread to the heart.
Implications:
- Cardiac metastasis should be considered in the differential diagnosis for patients with HCC and cardiac symptoms.
- Regular cardiac surveillance may be warranted in select HCC patients post-treatment.
- This rare presentation emphasizes the systemic nature of advanced hepatocellular carcinoma.
