Multimodality Imaging in the Evaluation of Cardiovascular Manifestations of Malignancy
Figure 3
Teratoma. A well-circumscribed solid mass is present adjacent to the right atrial appendage ((b), (c), (f) asterisk). Foci of low attenuation are identified within it on noncontrast axial MDCT ((a), white arrows). Similar areas can be seen on the T1-weighted image ((d), white arrow) and show signal “dropout” with a fat-suppressed sequence ((e), white arrow). The presence of fat in a mixed density mediastinal lesion raised the possibility of teratoma, and this diagnosis was confirmed at pathology.
