Insights
A rare cardiac hemangioma, a benign tumor, was incidentally discovered in a patient. Surgical resection was successful, confirming cavernous hemangioma diagnosis and leading to full recovery.
Area of Science:
- Cardiology
- Oncology
Background:
- Cardiac hemangiomas are rare benign tumors, with cavernous hemangioma being the most common type.
- While often asymptomatic, cardiac hemangiomas pose risks of serious complications including embolism, arrhythmia, and sudden death, necessitating consideration for surgical resection.
Purpose of the Study:
- To report a case of incidentally discovered cardiac hemangioma in a patient undergoing follow-up for breast cancer.
- To highlight the diagnostic features and successful surgical management of a cavernous hemangioma.
Main Methods:
- Incidental finding of a cardiac tumor via imaging studies during breast cancer follow-up.
- Transthoracic echocardiography and contrast-enhanced computed tomography (CT) for characterization.
- Surgical resection and histopathological examination for definitive diagnosis.
Main Results:
- A 12x16 mm, poorly mobile, highly echogenic mass with clear margins was identified in the right atrium.
- CT showed a round tumor with no obvious enhancement, atypical for typical contrast-enhanced cardiac hemangiomas.
- Histopathological examination confirmed the diagnosis of cavernous hemangioma.
Conclusions:
- Cardiac hemangiomas, even those without contrast enhancement on CT, can be successfully diagnosed and treated surgically.
- Prompt surgical intervention for symptomatic or high-risk cardiac hemangiomas is crucial for preventing severe complications.
Abstract:
Cardiac hemangioma is a rare benign tumor, and the cavernous type accounts for 50~60% of all cardiac hemangiomas. Although most cases are asymptomatic, the risk of serious complications, such as embolism, arrhythmia, tumor rupture, coronary artery obstruction, or sudden death, is high, and surgical resection should be considered. In a 60-year-old woman, follow-up imaging studies after a left breast cancer operation incidentally revealed a cardiac tumor in the right atrium. Transthoracic echocardiography showed a poorly mobile, highly echogenic 12×16 mm mass with clear margins, and contrast-enhanced computed tomography (CT) showed a round tumor with no obvious enhancement. The tumor was resected with an atrial wall and diagnosed as a cavernous hemangioma on histopathological examination. Cardiac hemangiomas are enhanced using contrast medium; however, some cases have no contrast enhancement. Histopathological examination confirmed this diagnosis. The patient was discharged on postoperative day 11 in a good condition.
