What do you see?
Post-repair Tetralogy of Fallot with Contegra conduit and branch pulmonary artery stenosis
D-transposition of the great arteries after arterial switch with branch pulmonary artery stenosis
Dilated pulmonary artery with peripheral branch stenosis in Noonan syndrome
Correct! The correct answer is "Dilated pulmonary artery with peripheral branch stenosis in Noonan syndrome".
 
Marked pulmonary artery dilatation with segmental branch stenoses creates a “radioactive-like” pattern on imaging, an unusual but characteristic finding in Noonan syndrome.

 
Good try! The correct answer is "Dilated pulmonary artery with peripheral branch stenosis in Noonan syndrome".
