Electrical Storm in a Patient With Rosai-Dorfman Disease With Intracardiac Masses and Myocardial Infiltration.

A 47-year-old woman with Rosai-Dorfman disease (RDD) presented with an electrical storm with sustained ventricular tachycardia. Echocardiography and computed tomography revealed an intracardiac mass involving the right atrium and left ventricle. Positron emission tomography demonstrated fluorodeoxyglucose avidity of the mass and myocardial infiltration; the electrical storm was attributed to this feature.

Triple rule-out cardiac computed tomography: is it finally a reality?

Acute coronary syndrome (ACS), pulmonary embolism and acute aortic syndrome are the most common causes of life threatening chest pain. The triple rule-out CT (TRO CT) has emerged as a technology that can simultaneously visualize the coronary arteries, aorta and pulmonary arteries as well as other intrathoracic structures. It has been proposed as a one-stop imaging modality in patients who present to the emergency department with low to intermediate risk of ACS in whom pulmonary embolism and/or acute aortic syndrome are also considered.

Dual-source 256-MDCT for diagnosis of anomalous pulmonary venous drainage in pediatric population.

Objective: The purpose of this study is to describe the MDCT findings of anomalous pulmonary venous drainage (APVD) in a pediatric population using a 256-MDCT dual-source scanner with a high-pitch protocol.

Conclusion: MDCT is a fast and noninvasive technique that allows detailed and comprehensive visualization of APVD characteristics in a pediatric population. High-pitch acquisitions with scanners using a high volume of coverage permit low radiation doses and are an accurate modality for assessing these patients.
