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.

Cavernous hemangioma of left atrial appendage in 66-year-old female.A. Transverse double inversionrecovery MR image shows intermediate signal intensity mass (arrows) in left atrial appendage.B. Transverse triple inversion-recovery MR image shows hyperintense mass (arrows) with smooth margin.C. Coronal gadolinium-enhanced double inversion-recovery MR image shows strong enhancement of lesion (arrows).D. Gross specimen with cut section demonstrates trabecular, hemorrhagic, and cystic appearance of mass.

Mentions: Hemangiomas are benign vascular tumors that comprise approximately 5-10% of benign tumors (5). Cardiac hemangiomas are heterogeneous as depicted on precontrast CT images and are intensely enhanced as seen on CT images obtained after the administration of a contrast material. As with hepatic hemangiomas, these tumors typically show intermediate signal intensity as seen on T1-weighted images and become hyperintense as seen on the T2-weighted images (Fig. 8) (13).
