    Area of Interest: Head and neck; Imaging Technique: Conventional radiography;
     
     
  • Figure 2
    Axial unenhanced CT image obtained with bone window settings

    Expansile cystic mass in the left maxillary sinus, containing a displaced third molar tooth (yellow arrow).

     
    Area of Interest: Head and neck; Imaging Technique: CT;
     
     
  • Figure 3
    Coronal unenhanced CT image obtained with bone window settings

    Large cystic mass arising in maxilla that displaces the floor of the left maxillary sinus (making it convex upwards). Cortical breakthrough of the inferolateral aspect of the mass is seen (yellow arrow).

     
    Area of Interest: Head and neck; Imaging Technique: CT; Special Focus: Cysts;
