Insights
A patient experienced a stroke due to a suspected left ventricular myxoma. Surgery revealed a pedunculated thrombus, highlighting the importance of definitive pathological diagnosis over initial clinical presentation.
Area of Science:
- Cardiovascular Medicine
- Pathology
- Neurology
Background:
- Cerebral vascular accidents can arise from cardiac masses.
- Left ventricular myxomas are primary cardiac tumors with potential embolic risks.
- Accurate diagnosis of cardiac masses is crucial for appropriate treatment.
Observation:
- A 35-year-old male presented with a stroke attributed to a left ventricular mass.
- Transesophageal echocardiography suggested a myxoma.
- Surgical resection of the mass was performed.
Findings:
- Pathological examination revealed a pedunculated thrombus, not a myxoma.
- The clinical and gross features were initially misleading, mimicking myxoma.
- Definitive diagnosis was established post-operatively.
Implications:
- This case underscores the critical role of histopathology in differentiating cardiac masses.
- It highlights potential discrepancies between imaging/clinical suspicion and final diagnosis.
- Accurate pathological diagnosis is essential for understanding embolic stroke etiology and prognosis.
Abstract:
A 35-year-old man with cerebral vascular accident due to a left ventricular myxoma, had his diagnosis cleaned up by the transesophageal echocardiography. The patient underwent heart surgery to remove the tumor. The final pathologic diagnosis was therefore pedunculated thrombus of the left ventricle although the clinical findings and gross morphologic features of the mass were highly suggestive of myxoma.
