**7. Pericardial disease**

Pericardial disease in cancer patients is relatively common. Pericardial effusion, cardiac tamponade and pericarditis can appear during several types of chemotherapy (anthracyclines [25], cyclophosphamide [26] and cytarabine [27]) but are especially due to radiotherapy. Constrictive pericarditis is more often associated with radiation-induced cardiotoxicity [28]. Additionally, pericardial disease may be secondary to cardiac metastasis.

Echocardiography is the first-line cardiac imaging for the diagnosis of cancer therapy-related pericarditis. It is useful for evaluating the degree of pericardial thickening, the presence of constrictive physiology and the presence and quantification of a pericardial effusion, as guidance of pericardiocentesis and for patient follow-up.
