Magnetic resonance imaging (MRI) showed a T2-hyperintense signal involving the dens (C2), accompanied by an extensive inflammatory reaction involving the retropharyngeal space [Figure 1a]. Computed tomography (CT) scan also documented early dens erosion [Figure 1b and c].
(a) Sagittal T2-weighted MR image (STIR) performed at the end of antibiotic therapy showing a reduction of the inflammatory process but initial ongoing of deformity of the dens. Sagittal (b) and coronal (c) CT scan showing pronounced increasing of the erosion of the dens of C2
