Insights
A rare pericardial hemangioma presented as heart failure symptoms, causing bloody pericardial effusion. Advanced imaging accurately diagnosed this benign tumor before surgery.
Area of Science:
- Cardiology
- Oncology
- Pathology
Background:
- Pericardial tumors are rare, often presenting with nonspecific symptoms.
- Bloody pericardial effusion is typically associated with malignancy, complicating diagnosis.
Abstract:
A 78-year-old woman presented with leg edema and exertional dyspnea. Echocardiography revealed a smooth-surfaced mass adjacent to the left atrium in the pericardial cavity with a massive pericardial effusion. Pericardiocentesis resulted in the drainage of a bloody effusion. Magnetic resonance imaging documented a mass having isointensity on T1- and hyperintensity on T2-weighted images. In addition, the mass was evenly enhanced with gadolinium 10 min after administration. By surgical resection, a 25 × 30 mm in diameter tumor was excised together with a left atrial wall portion. The pathological examination made a final diagnosis as hemangioma. Based on these findings, we report the rare case of pericardial hemangioma with a bloody pericardial effusion, which presented with heart failure symptoms. Although bloody pericardial effusion is considered a supportive characteristic for malignant tumors, we could preoperatively make a precise diagnosis of benign hemangioma by means of several imaging modalities.

A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
