主　　题：Seizure Rupture Temporalis Muscle Pedi-atric 

摘      要：Seizures are one of the most common pediatric neu-rologic disorders. Many complications secondary to seizures have been described in the literature including head trauma, fractures, drowning and burns. How-ever, to the best of our knowledge, rupture of the myotendinous insertion of the temporalis muscle on the mandible secondary to a seizure has never been described in the literature. We report the case of a unilateral temporalis muscle rupture in a 16-year-old boy who developed unilateral facial swelling following new onset tonic-clonic seizures. We emphasize on the computed tomography and magnetic resonance imag-ing findings in this case report. Two mechanisms have been proposed to explain such an injury. The favored mechanism in our patient is a pull on the temporalis myotendinous insertion on the mandible following vig-orous and brisk deviation of the head and neck during seizure. Radiologists should be familiar with this type of injury following seizures in order to prevent misdiagno-sis and subsequently mistreatment.
