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.

Papillary fibroelastoma of aortic valve in 60-year-old femaleA. ECG-gated multidetector CT image demonstrates abnormal thickening of aortic valve (arrow).B, C. Oblique cine MR images demonstrates small mass (arrows) attached to aortic valve that was moving according to valvular motion.D. Oblique transverse triple inversion-recovery MR image demonstrates slightly high signal intensity of small mass (arrow).E. Surgical specimen shows small mass with many branching frond-like structures.F. Photomicrograph (Hematoxylin & Eosin staining, ×150) shows fibrous core and scattered smooth muscle cells within papillary projections.

Figure 5: Papillary fibroelastoma of aortic valve in 60-year-old femaleA. ECG-gated multidetector CT image demonstrates abnormal thickening of aortic valve (arrow).B, C.

Mentions: Papillary fibroelastomas are benign endocardial papillomas that mainly affect the cardiac valves and account for approximately 75% of all cardiac valvular tumors (9). Papillary fibroelastomas are usually not observed on CT or MR images as they are small (< 1.5 cm in diameter) and are attached to the moving valves (9). MR imaging typically demonstrates the presence of a mass on a valve leaflet or on the endocardial surface (Fig. 5). These tumors can create turbulence in the blood flow, which might be demonstrated with the use of cine MR imaging.
