Primary cardiac synovial sarcoma presenting with brain metastases

Area of Science:

• Cardiology
• Oncology
• Pathology

Background:

• Primary cardiac tumors are rare, with synovial sarcoma being exceptionally uncommon.
• Primary cardiac sarcomas, though rare, frequently metastasize to the brain.
• These aggressive tumors are associated with poor patient prognoses.

Observation:

• A 29-year-old female presented with neurological symptoms including blurred vision, headache, nausea, and vomiting.
• Radiological studies revealed brain lesions.
• Echocardiography incidentally identified a left atrial mass originating from the atrial free wall and pulmonary veins.

Findings:

• The patient underwent emergency cardiac surgery for resection of the left atrial mass.
• Histopathological examination confirmed the diagnosis of primary cardiac synovial sarcoma.
• This case highlights an unusual presentation of cardiac synovial sarcoma in the left atrium.

Implications:

• This case underscores the importance of considering rare cardiac tumors in patients with unexplained neurological symptoms.
• Early diagnosis and surgical intervention are crucial for managing primary cardiac synovial sarcoma.
• Further research into the behavior and treatment of primary cardiac sarcomas is warranted.
