The disastrous "sun ray" sign in cardiac magnetic resonance: an indicator of angiosarcoma.

ABSTRACT

Distinguishing the benign and malignant cardiac masses is usually a diagnostic challenge, and safe, non-invasive, and reliable techniques are necessary to avoid any delay in treatment. The previously described "sun ray" appearance is an important sign in the diagnosis of cardiac angiosarcoma, and in this report we present 3-T magnetic resonance imaging findings to distinguish the rare but fatal cardiac angiosarcoma.
