    MR Imaging
     

    Axial T1 weighted image showing an intermediate signal lesion within the left sphenoid sinus (arrow).

     
    Area of Interest: Ear / Nose / Throat; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Cysts;

    Axial T2 weighted image showing a predominantly low signal lesion with peripheral high signal within the left sphenoid sinus (arrow).

     
    Area of Interest: Ear / Nose / Throat; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Cysts;

    Axial [A] and coronal [B] T1 weighted post IV Gadolinium images showing peripheral enhancement of the lesion (arrows).

     
    Area of Interest: Ear / Nose / Throat; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Cysts;

    Coronal T2W images [A and B] showing a low signal lesion with peripheral high signal within the left sphenoid sinus (long arrows). Note the relationship to the left foramen rotundum (short arrow in A).

     
    Area of Interest: Head and neck; Imaging Technique: MR; Procedure: Education; Special Focus: Obstruction / Occlusion;
     
     
  • Figure 2
    Axial CT

    Axial CT images from inferior [A] to superior [D] showing the position of the opacified left sphenoid air cell (arrows) in relation to the remainder of the sphenoid sinus.

     
    Area of Interest: Head and neck; Imaging Technique: CT; Procedure: Normal variants; Special Focus: Obstruction / Occlusion;
     
     
  • Figure 3
    Coronal CT

    Coronal CT images showing the course of the left foramen rotundum (arrows). There is bony dehiscence of the roof of the opacified sphenoid sinus at the internal opening of the foramen rotundum (arrow in C).
