case_images: A cranial magnetic resonance imaging (MRI) was performed, which showed complete opacification and high signal in the mastoid air cells, middle ear, and petrous apex on T2 scans on the right side (Figure 1).
case_images: Coronal reformatted CT image (before treatment) shows hyperdensity in right mastoid
  cells, middle ear and petrous apex. Also destruction in petrous apex is seen.

case_images: fig2-2050313X20966119
case_images: CT images showed erosion in the petrous apex indicative of petrous apicitis on the right side (Figure 2). Concomitant right acute mastoiditis with petrositis, right orbitofacial pain, and right abducens palsy was indicative of Gradenigo's syndrome.
case_images: Axial CT image (after treatment) identifies complete resolution of the lesions in right
  ear and tympanostomy tube.
