RESUMO
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.

Cardiac masses represent a diagnostic challenge because decisions about treatment are based on imaging techniques. Echocardiography, magnetic resonance (MR) and computed tomography (CT) are fundamental for the detection, characterization, and staging of cardiac masses as well as for planning their treatment. Most primary cardiac tumors are benign; myxomas, papillary fibroelastomas, and lipomas are the most common. The location of the tumors and its characteristics on CT and MR orient the etiologic diagnosis in most cases. This article describes the protocols for CT and MR studies of cardiac masses as well as the morphologic findings, predominant locations, and most useful characteristics for characterizing benign cardiac masses and establishing the differential diagnosis with malignant cardiac tumors and non-neoplastic pseudotumors.

Los tumores cardíacos malignos son menos frecuentes que los tumores benignos; pueden ser primarios y secundarios. Los secundarios o metastásicos son entre 20 y 40 veces más frecuentes que los primarios, con una incidencia estimada del 0,05%. Las lesiones pseudotumorales no neoplásicas pueden presentarse como masas cardíacas con características de imagen que pueden plantear el diagnóstico con neoplasias. El objetivo de este trabajo es presentar los tumores cardíacos malignos y las lesiones pseudotumorales haciendo hincapié en los hallazgos en TC y RM y en las características que permiten diferenciarlos de los tumores cardíacos benignos (AU)

Las masas cardíacas son un reto diagnóstico porque las decisiones terapéuticas se basan en los hallazgos de las técnicas de imagen. La ecocardiografía, la resonancia magnética (RM) y la tomografía computarizada (TC) son fundamentales para la detección, caracterización, estadificación y planificación del tratamiento. La mayoría de los tumores primarios son benignos; los más frecuentes son el mixoma, el fibroelastoma papilar y el lipoma. La localización del tumor y sus características en la TC y la RM orientan el diagnóstico etiológico en la mayor parte de los casos. Se describen los protocolos de estudio de TC y RM de las masas cardíacas, así como los hallazgos morfológicos, las localizaciones preferentes y las características más útiles para caracterizar las masas cardíacas benignas y establecer el diagnóstico diferencial con los tumores cardíacos malignos y las lesiones pseudotumorales no neoplásicas (AU)
