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.

Cardiac rhabdomyoma in newborn with tuberous sclerosisA. Gadolinium-enhanced T1-weighted MR image shows abnormal enhancing lesions (arrows) in both caudate nuclei and frontal lobes, indicating presence of tubers.B. Sagittal T1-weighted spin echo MR image shows isointense mass (arrows) in septum and anterior wall of left ventricle.C. Transverse gadolinium-enhanced T1-weighted spin echo MR image shows mild enhancement of mass (arrows).

Mentions: Rhabdomyomas are the most common cardiac tumors in infancy and childhood, and are often associated with tuberous sclerosis in up to 50% of cases (12). Most patients are asymptomatic, and rhabdomyomas generally regress spontaneously. These tumors originate within the myocardium, typically in the ventricles, and multiple lesions may be present in up to 90% of cases (12). Rhabdomyomas appear isointense to marginally hyperintense as compared with the myocardium as seen on T1-weighted images and hyperintense as seen on T2-weighted images (Fig. 7).
