    Axial image. Homogeneous soft-tissue lesion located in the upper inner right orbital quadrant (asterisk) surrounding the globe.

     
    Area of Interest: Head and neck; Imaging Technique: CT; Procedure: Education; Special Focus: Lymphoma;

    Axial image. Homogeneous soft-tissue lesion located in the upper inner right orbital quadrant (asterisk) above the globe.

     
    Area of Interest: Head and neck; Imaging Technique: CT; Procedure: Education; Special Focus: Lymphoma;

    Coronal image. The soft-tisue density lesion surrounding the right globe has a small extraconal component extending towards the upper eyelid.

     
    Area of Interest: Head and neck; Imaging Technique: CT; Procedure: Education; Special Focus: Lymphoma;

    Coronal view. The lesion involves right superior rectus muscle.

     
    Area of Interest: Haematologic; Imaging Technique: CT; Procedure: Education; Special Focus: Lymphoma;

    Sagittal view. The lesion had a wide plane of contact with the optic nerve.

     
    Area of Interest: Head and neck; Imaging Technique: CT; Procedure: Education; Special Focus: Lymphoma;

    Axial T1W image. The right sided lesion surrounding the globe is mildly hypointense compared with extraocular muscles.

     
    Area of Interest: Head and neck; Imaging Technique: MR; Procedure: Education; Special Focus: Lymphoma;

    Axial T2W image. The right-sided lesion is hyperintense compared with extraocular muscles.

     
    Area of Interest: Head and neck; Imaging Technique: MR; Procedure: Education; Special Focus: Lymphoma;

    Axial T1W post-Gd. The right orbital lesion demonstrates homogeneous enhancement.

     
    Area of Interest: Head and neck; Imaging Technique: MR; Procedure: Education; Special Focus: Lymphoma;

    Coronal T2W image. There is broad-based contact between the right orbital lesion and optic nerve sheath complex representing perineural infiltration.

     
    Area of Interest: Abdomen; Imaging Technique: MR; Procedure: Education; Special Focus: Lymphoma;

    Sagittal T1W image. There is broad-based contact between the optic nerve and lesion representing perineural infiltration.

     
    Area of Interest: Head and neck; Imaging Technique: MR; Procedure: Education; Special Focus: Lymphoma;
