A 21-year-old man presented with new-onset seizures and brain abscess. Echocardiography and cardiac magnetic resonance imaging revealed underlying Ebstein anomaly, secundum atrial septal defect, and cor triatriatum dexter. The elevated right heart pressures shunting through the septal defect and transient bacteremia were the likely mechanisms for his presentation. (Level of Difficulty: Intermediate.).
Keywords: ASD, atrial septal defect; ECG, electrocardiography; Ebstein anomaly; MRI, magnetic resonance imaging; RV, right ventricle; congenital heart defect; echocardiography.
