62 year old female with aneurysm of the membranous septum.
Technique: MRI 1,5T; Steady State Free Precession (SSFP) four chambers view; TR (repetition time) 3,6 msec, TE (echo time) 1,6 msec, Flip angle 65°, Slice thickness 4mm, Image matrix 256 × 256.
Finding: Steady State Free Precession (SSFP) four chambers view in systole (a) and diastole (b) show an AMS (20 × 15 mm) arising from membranous septum beneath the septal leaflet of the tricuspid valve, bulging into right ventricle, without any thrombus or shunt flow between the ventricles (asterisk).
