    Primary pericardial tumours are rare. The most common benign lesions are pericardial cysts and lipomas, while mesothelioma is the most common primary malignant pericardial neoplasm. Other malignant tumours include a wide variety of sarcomas, lymphoma and primitive neuroectodermal tumour. Signs and symptoms are generally nonspecific.

    CT and MRI imaging allow further characterisation and may, in some cases, provide diagnostic findings. Both benign and malignant tumours may result in compression of vital mediastinal structures. Malignant lesions may also directly invade structures, such as the myocardium and great vessels, and result in metastatic disease.
