Fig 3. Axial postgadolinium FSE-IDEAL T1-weighted images (A–C) demonstrate a polymorphous adenocarcinoma of the right maxillary sinus extending through the pterygopalatine fossa to the inferior orbital fissure. Coronal postgadolinium T1-weighted FSE-IDEAL image (D) is diagnostically limited due to unfortunate fat-water mismap at the right pterygopalatine fossa (arrows).
