Core Tip

Core tip: We report the unique case of a unilateral temporalis muscle rupture following new onset tonic-clonic seizures in a 16-year-old boy. The favored mechanism in our patient is a pull on the temporalis myotendinous insertion on the mandible following vigorous and brisk deviation of the head and neck during seizure. Although this is a rare entity, it is important to be familiar with such type of injury in a patient who develops unilateral facial swelling and pain following tonic-clonic seizures in order to prevent misdiagnosis and mistreatment.
