Conclusion
There is no specific investigation for diagnosing cardiac lymphangiomas, and though benign, they should be considered in the differential diagnosis of other malignant diseases of the mediastinum and definitive pathologic diagnosis is mandatory. Given the increased risk of uncontrolled bleeding related to percutaneous biopsy, the definite diagnosis is usually obtained with open surgical biopsy.
Discussion
The pericardial mass of our case had no cleavage plane between the myocardium and the tumor. Because of this, rather than a total resection, with very high operative risk, a biopsy was preferred. The pathology specimen showed a benign tumor and the patient was referred to the cardiologist for regular follow-up.
