Insights
Cardiac myxoma, a common benign heart tumor, can cause brain metastases through embolization. Early echocardiography is crucial for diagnosing heart tumors in patients with brain lesions to prevent strokes.
Area of Science:
- Cardiology
- Neurology
- Oncology
Background:
- Cardiac myxoma is the most prevalent benign cardiac neoplasm.
- Cerebral metastases typically arise from primary brain tumors or systemic cancers.
- Tumor embolization from cardiac sources is an uncommon but significant cause of cerebrovascular events.
Observation:
- A case presented with multiple brain metastases, initially presumed to be from a primary brain malignancy.
- Diagnostic workup revealed an underlying cardiac myxoma as the source of tumor emboli.
- Transthoracic echocardiography was instrumental in identifying the cardiac mass.
Findings:
- Cardiac myxoma, though rare, can manifest as multiple cerebral lesions due to tumor embolization.
- Early detection of cardiac myxoma is critical in patients presenting with unexplained neurological deficits.
- Surgical resection of cardiac myxoma offers a definitive treatment and prevents further embolic events.
Implications:
- Highlights the importance of considering cardiac tumors in the differential diagnosis of multiple brain metastases.
- Emphasizes the role of echocardiography in the early detection of cardiac myxoma.
- Underscores the effectiveness of surgical management in preventing recurrent embolic strokes from cardiac myxoma.
Abstract:
Cardiac myxoma is the most common benign heart tumor. We report a case with multiple brain metastases, presumably due to tumor embolization. It is important to perform transthoracic echocardiography at a very early stage to exclude structural heart disease in patients with signs of multiple brain metastases. Though myxoma is a rare cause of cerebral embolism, detection of this tumor is relatively easy and surgical resection of myxoma is usually a permanent measure to prevent subsequent stroke.
