  • Figure 1
    Axial CT
     

    The formation is intensely hyperdense and occupies the cartilage of the nasal septum. The almost complete symmetry in disposition of finding justifies the absence of typical symptomatology with unilateral ventilation.

     
    Area of Interest: Head and neck; Imaging Technique: CT; Procedure: Imaging sequences; Special Focus: Foreign bodies;

    The window for bone allows to highlight the "brightness" of the foreign body indicating the presence of metallic material.

    Sagittal reconstructed CT images
     

    Reconstructions in the sagittal plane showing in greater detail the cartilage perforation around the formation.

     
    Area of Interest: Head and neck; Imaging Technique: CT; Procedure: Computer Applications-General; Special Focus: Foreign bodies;

    In Figure b the image obtained with bone window is shown.

  • Figure 3
    CT scout

    CT scout shows the two-discs morphology of the formation, supporting the hypothesis of a button battery nature.

  • Figure 4
    3D reconstruction

    Three-dimensional reconstruction of Computed Tomography images showing position (a) and the shape (b) of the foreign body.
