Intraparenchymal Brain Abscess in an Adult Male With Underlying Ebstein Anomaly and Cor Triatriatum Dexter

Abstract

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. )

Paradoxical septic embolism in an Ebstein's anomaly patient leading to brain abscess: A case report

“…EA has been commonly reported in association with atrial septal defect (ASD) or PFO, right ventricular outflow tract obstruction, and WPW syndrome, as demonstrated in the present case [ 2 , 4 ]. To the best of our knowledge, this is the 5th case report of EA with PFO/ASD-associated septic paradoxical embolism, but the first case report in the setting of septic emboli originating from a lower extremity abscess [ 3 , [5] , [6] , [7] ].…”
