Figure 3: MR imaging of a 54-year-old male (Case 2) with AFIFS. (A) Axial T1 post-contrast fat-saturated MR image demonstrates loss of enhancement of the inferior turbinate (arrow) and of most of the walls of the left maxillary sinus (arrowheads), but also of the retromaxillary (asterisk) and premaxillary (open arrow) fat. (B) Coronal T1 post-contrast fat-saturated MR demonstrates loss of enhancement of orbital fat (arrow) and the inferior rectus muscle (arrowhead) on the left side.
