We report the case of a 56-year-old male patient affected by a severe form of Ebstein's anomaly (type C of Carpentier classification) with secundum atrial septal defect, who presented to the emergency department with impaired consciousness, seizures, and trismus. The brain computed tomography scan showed evidence of a mass located in the frontal lobe, confirmed by brain MRI consistent with brain abscess. Both echocardiography and cardiac MRI showed no evidence of valvular vegetation. This case shows how the combination of increased atrial pressure and bidirectional shunt through atrial septal defect may lead to paradoxical embolization.

Abstract

We report the case of a 56-year-old male patient affected by a severe form of Ebstein's anomaly (type C of Carpentier classification) with secundum atrial septal defect, who presented to the emergency department with impaired consciousness, seizures, and trismus. The brain computed tomography scan showed evidence of a mass located in the frontal lobe, confirmed by brain MRI consistent with brain abscess. Both echocardiography and cardiac MRI showed no evidence of valvular vegetation. This case shows how the combination of increased atrial pressure and bidirectional shunt through atrial septal defect may lead to paradoxical embolization.
