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 ventricular fibroma in 48-year-old female.A. ECG-gated multidetector CT image shows myocardial thickening (arrows) and spotty calcification (arrowhead) in lateral wall of left ventricle.B. Transverse double inversion-recovery MR image shows hypointense mass (arrows) in myocardium of left ventricle.C. Transverse triple inversion-recovery MR image also shows hypointense mass (arrows) in myocardium of left ventricle.D. Delayed MR image with suppression of normal myocardial signal 10 minutes after administration of gadolinium demonstrates hyperenhancement of mass (arrows).

Figure 6: Left ventricular fibroma in 48-year-old female.A. ECG-gated multidetector CT image shows myocardial thickening (arrows) and spotty calcification (arrowhead) in lateral wall of left ventricle.B. Transverse double inversion-recovery MR image shows hypointense mass (arrows) in myocardium of left ventricle.C. Transverse triple inversion-recovery MR image also shows hypointense mass (arrows) in myocardium of left ventricle.D. Delayed MR image with suppression of normal myocardial signal 10 minutes after administration of gadolinium demonstrates hyperenhancement of mass (arrows).

Mentions: Fibromas are neoplasms that mainly affect infants and children, being the second most common tumors found in this age group (10). Grossly, the lesions are solid tumors that arise within the myocardium and can grow to a size that obliterates the cavity. The use of CT shows fibromas as homogeneous masses with soft-tissue attenuation, which may be either sharply marginated or infiltrative. Calcification is often observed (Fig. 6A) (10). These tumors are normally homogeneously isointense to hypointense relative to the myocardium as seen on T1- and T2-weighted images due to a dense, fibrous nature. For the same reason, these tumors often show delayed enhancement on gadolinium-enhanced MR images (Fig. 6B-D) (11).
