  • Figure 1
    a) Axial, b) sagital pre-contrast brain MRI scan (T2WI)
     

    The lesion in the right nasal cavity extends into the right frontal lobe. The intracranial mass is surrounded by edema.

     
    Area of Interest: Head and neck; Oncology; Imaging Technique: MR; Special Focus: Neoplasia;

    A slightly hyperintense mass in the right nasal cavity is seen, extending into the right frontal lobe The intracranial mass is surrounded by edema.

     
    Area of Interest: Head and neck; Oncology; Imaging Technique: MR; Special Focus: Neoplasia;
     
     
  • Figure 2
    a) Axial, b) coronal pre-contrast brain MRI scan (T1W1):
     

    the lesion in the right nasal cavity extends into the right frontal lobe

     
    Area of Interest: Head and neck; Oncology; Imaging Technique: MR; Special Focus: Neoplasia;

    hypointense lesion in the right nasal cavity which extends into the right frontal lobe

     
    Area of Interest: Head and neck; Oncology; Imaging Technique: MR; Special Focus: Neoplasia;
     
     
  • Figure 3
    a) Axial, b) coronal post-contrast brain MRI scan (T1W1):
     

    heterogeneous enhancement of the lesion after intravenous administration of gadopentetate dimeglumine is seen.

     
    Area of Interest: Head and neck; Oncology; Imaging Technique: MR; Procedure: Contrast agent-intravenous; Special Focus: Neoplasia;

    a heterogeneously enhancing mass is present in the right nasal cavity which extends through the skull base

     
    Area of Interest: Head and neck; Oncology; Imaging Technique: MR; Procedure: Contrast agent-intravenous; Special Focus: Neoplasia;
     
     
  • Figure 4
    Sagital post-contrast brain MRI scan (T1W1):

    the sagital image shows the intracranial extension of the heterogeneously enhancing lesion.

     
    Area of Interest: Oncology; Imaging Technique: MR; Special Focus: Neoplasia;
     
     
  • Figure 5
    Axial pre-contrast brain MRI scan ( DWI) :
     

    DWI (5a) demonstrated low signal intensity with increased ADC values (5b). No restriction of diffusion was observed.

     
    Area of Interest: Head and neck; Oncology; Imaging Technique: MR; Special Focus: Neoplasia;

    DWI (5a)demonstrated low signal intensity with increased ADC values (5b). No restriction of diffusion was observed.
