Patient
female, 3 year(s)
 
 
  • Figure 1
    Cranial CT
     

    Soft tissue mass over the right frontal base, with calcifications.

     
    Area of Interest: Head and neck; Imaging Technique: CT;

    After intravenous contrast administration. Heterogeneous enhancement of the lesion.

     
    Area of Interest: Head and neck; Imaging Technique: CT;
     
     
  • Figure 2
    Helical CT. Coronal, 3D reconstructions
     

    Coronal reconstruction. The mass neither passes through the etmoidal cribose plate nor the orbital roof.

     
    Area of Interest: Head and neck; Imaging Technique: CT;

    3D reconstruction. Asymmetry related to the expansion of the olfactory depression, displacement of the crista galli.

     
    Area of Interest: Head and neck; Imaging Technique: CT;
     
     
  • Figure 3
    MR study
     

    Sagittal FSE T1. Mass with a lower signal intensity than the brain parenchyma. Displacement of the adjacent structures.

     
    Area of Interest: Head and neck; Imaging Technique: MR;

    Axial FSE Pd. The lesion appears hyperintense on sequences of long TR.

     
    Area of Interest: Head and neck; Imaging Technique: MR;

    Axial FSE T2 FLAIR. Heterogeneous structure related to the presence of inner calcifications and blood.

     
    Area of Interest: Head and neck; Imaging Technique: MR;

    Axial FSE T1 after intravenous contrast administration. Moderate, heterogeneous enhancement.

     
    Area of Interest: Head and neck; Imaging Technique: MR;

    Coronal FSE T1 after intravenous contrast administration. Depicts the relation of the right frontal mass and the floor of the anterior fossa.

     
    Area of Interest: Head and neck; Imaging Technique: MR;
     
     
  • Figure 4
    Espectroscopy by means MR (H)

    There are lactates and lipids indicative of non specific necrosis.
