Radiologic evaluation of right ventricular outflow tract myxomas.

A 22-year-old man was referred for palpitations. On transthoracic echocardiography, he was found to have a right ventricular outflow tract mass. Further cardiac imaging was conducted by means of transesophageal echocardiography, computed tomography, and cardiac magnetic resonance. Complete surgical resection of the tumor was achieved, and pathologic examination revealed the lesion to be a myxoma. Cardiac tumors located in the right ventricular outflow tract are rare and can present unusual diagnostic and therapeutic challenges. Cardiac computed tomography and magnetic resonance are becoming more widely available and can be useful adjuncts in the management of such tumors.
