Kim EY, Choe YH, Sung K, Park SW, Kim JH, Ko YH - Korean J Radiol (2009)

Bottom Line: The purpose of this article is to provide a current review of the spectrum of multidetector CT (MDCT) and MRI findings for a variety of cardiac neoplasms.In the diagnosis of cardiac tumors, the use of MDCT and MRI can help differentiate benign from malignant masses.Knowledge of the characteristic MRI findings of benign cardiac tumors or thrombi can be helpful to avoid unnecessary surgical procedures.

ABSTRACT
The purpose of this article is to provide a current review of the spectrum of multidetector CT (MDCT) and MRI findings for a variety of cardiac neoplasms. In the diagnosis of cardiac tumors, the use of MDCT and MRI can help differentiate benign from malignant masses. Especially, the use of MDCT is advantageous in providing anatomical information and MRI is useful for tissue characterization of cardiac masses. Knowledge of the characteristic MRI findings of benign cardiac tumors or thrombi can be helpful to avoid unnecessary surgical procedures. Presurgical assessment of malignant cardiac tumors with the use of MDCT and MRI may allow determination of the resectability of tumors and planning for the reconstruction of cardiac chambers.

Left atrial myxosarcoma in 72-year-old female.A. Reformatted ECG-gated multidetector CT image shows irregular mass (arrow) with broad-base attachment to left atrium. Also, note minimal wall thickening (arrowheads) of interatrial septum due to tumor spread along left atrial wall and septum.B. Oblique double inversion-recovery MR image depicts hyperintense lesion (arrow) after gadolinium injection.C. Virtual angioscopic multidetector CT image shows irregular mass (arrow) near mitral valve (MV) and small polypoid mass (arrowhead).D. At surgery, presence of lobulated soft tissue mass (arrow) and small polypoid lesions were demonstrated (arrowheads).

Mentions: Myxosarcoma is a rare form of primary malignant tumors that is very difficult to differentiate from a myxoma (Fig. 11). The ratio between the incidence of myxomas and myxosarcomas is approximately 100: 0.8 and the prognoses of the two tumor types are very different (16). Myxosarcomas have local recurrences, involving the pulmonary artery, pericardium or pleura and distant metastases, with the brain being the site most affected (16).
