Invasive thymoma extending into the superior vena cava and right atrium: The value of multimodal cardiac magnetic resonance.

The purpose of this case report is to describe the multimodal cardiac magnetic resonance (CMR) imaging features of an invasive thymoma extending into the superior vena cava and right atrium. This unusual case indicates that multimodal CMR can not only reveal the morphological features of thymoma but also enable the identification of histological types, which provides a reasonable surgical plan in the perioperative management. < Invasive thymoma can invade the superior vena cava and extend into the right atrium. Multimodal cardiac magnetic resonance images have certain characteristics in the diagnosis of invasive thymoma.>.
