The destruction of bones and tissues may cause the current infection in the brain.A 55-year-old male patient applied to the emergency department for a left ear pain complaint. In his examination, he was conscious, but orientation and cooperation were not complete. The brain CT showed a mastoidectomy cavity on the left, but he had never been operated on.
