We report an exceedingly rare case of primary bronchogenic cyst in the outflow tract of the right ventricle in a 48-year-old woman. In our review of the world literature, we found only 1 other report of an intracardiac bronchogenic cyst. Our patient's only symptom was mild dyspnea not associated with physical exertion, and the cyst was resected successfully. We report clinical aspects of the case, diagnostic methods, surgical management, and histopathologic findings.
