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.

Hematogenous cardiac metastases from hepatocellular carcinomas in 50-year-old male.A. ECG-gated multidetector CT image shows marked thickening of right ventricular free wall (arrows).B. Gadolinium-enhanced transverse double inversion-recovery MR image shows diffuse thickening of right ventricular wall (arrows).C, D. Arterial (C) and delayed (D) CT images show multiple hepatocellular carcinomas with characteristic dynamic pattern of early enhancement and wash out (arrows).

Mentions: The epicardium is the site most often affected by metastases (18, 19). Spread is mainly via a retrograde route through the mediastinal lymphatics, leading to implantation in the epicardial surface of the heart. Other tumors such as melanomas and sarcomas usually spread hematogenously to the myocardium and epicardium through the coronary arteries, or less commonly, by the implantation of cancer cells through the vena cava (Fig. 13) (19). Hematogenous metastases in the heart and pericardium are normally accompanied by evidence of hematogenous metastases in other organs. In particular, pulmonary metastases are usually present (19).
