Summary
A rare cardiac tumor, a cavernous hemangioma, was diagnosed in a woman with new-onset left bundle branch block. The tumor involved the left ventricle and atrium, preventing surgical resection.
Area of Science:
- Cardiology
- Cardiovascular Surgery
- Diagnostic Imaging
Background:
- A 56-year-old woman presented with insomnia and nervousness.
- Previous electrocardiogram (ECG) two years prior was normal.
Observation:
- New-onset left bundle branch block on ECG.
- Echocardiography revealed a perimyocardial space-occupying lesion in the left ventricle.
- Magnetic resonance imaging (MRI) showed a 6x6x7 cm solid tumor inseparable from the left ventricle and left atrial wall.
- Coronary angiography identified atypical vessels from the right coronary artery.
- Endomyocardial biopsy results were equivocal.
Findings:
- Exploratory thoracotomy identified a large, livid tumor.
- The tumor's extensive involvement of the left ventricle and left atrium precluded resection.
- Surgical biopsy confirmed a diagnosis of cavernous hemangioma.
Implications:
- Cavernous hemangioma is a rare cardiac tumor that can present with conduction abnormalities.
- Advanced imaging techniques are crucial for diagnosis and surgical planning.
- Involvement of vital cardiac structures may necessitate conservative management.
