Radiology Cases of Mastoid Fracture

CT of mastoid fracture — Axial CT without contrast of the maxillofacial bones shows a linear lucent line through the lateral aspect of the right mastoid bone with resultant opacification of the mastoid air cells. There was associated diastasis of the right lambdoid suture.

CT of mastoid fracture — Axial CT without contrast of the maxillofacial bones shows a linear lucent line extending throughout the left mastoid bone with resultant opacification of the left mastoid air cells.

CT of pediatric mastoid bone fracture — Axial CT without contrast of the maxillofacial bones (left) shows a linear lucent line extending through the left mastoid bone without opacification of the left mastoid air cells along with a small amount of pneumocephalus which is better demonstrated on the axial CT of the temporal bone (right)
