[Imaging findings in cardiac masses. Part II: malignant tumors and pseudotumors].

Malignant heart tumors are less common than benign ones. They can be primary or secondary. Secondary or metastatic heart tumors are 20 to 40 times more common than primary malignant heart tumors, which have an estimated incidence of 0.05%. Non-neoplastic pseudotumors can present as cardiac masses, with imaging characteristics than can suggest the diagnosis of a tumor. The aim of this article is to describe and illustrate malignant heart tumors and pseudotumors, stressing the CT and MRI findings that make it possible to differentiate them from benign cardiac tumors.
