Seizures are one of the most common pediatric neurologic disorders. Many complications secondary to seizures have been described in the literature including head trauma, fractures, drowning and burns. However, 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 imaging 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 vigorous 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 misdiagnosis and subsequently mistreatment.
癫痫发作是最常见的儿科神经系统疾病之一。文献中已描述了许多癫痫发作继发的并发症，包括头部外伤、骨折、溺水和烧伤。然而，据我们所知，文献中从未描述过癫痫发作继发颞肌在下颌骨上的肌腱附着点破裂。我们报告了一名16岁男孩单侧颞肌破裂的病例，该男孩在新发性强直阵挛发作后出现单侧面部肿胀。我们在本病例报告中重点介绍计算机断层扫描和磁共振成像结果。已提出两种机制来解释这种损伤。在我们的患者中，最有可能的机制是癫痫发作期间头颈部剧烈快速偏斜后，颞肌在下颌骨上的肌腱附着点受到牵拉。放射科医生应熟悉癫痫发作后的这种损伤类型，以防止误诊及随后的误治。
