Abstract：
Traumatic hemorrhage of the thyroid gland resulting from blunt injury to the neck is a very rare event. Particular neck positions can expose the thyroid to trauma, especially in motor vehicle collisions, falls, direct blows, or sport activities. Preexisting conditions such as goiters, adenomas, and cysts can increase the risk of bleeding, reducing the force required to rupture the gland and make the thyroid more prone to injury. The authors report the case of a 53-year-old man who was involved in a fire while working on maintenance of a liquid petroleum gas (LPG)-powered car. He subsequently presented to the emergency department with painful swelling of his right anterior neck with a palpable mass. CT scan showed a right thyroid hemorrhagic cyst. The worker reported that he had jumped into the car trunk to extinguish the fire and covered the gas tank nozzle with his own body to prevent dispersal of the accelerant. In this case, the medico-legal evaluation was useful to delineate between natural and traumatic causes of the injury. Medico-legal assessment is key in understanding the dynamics involved in work-related events to identify any legal responsibilities of the worker or the employer.
摘要：
颈部钝性损伤导致的甲状腺外伤性出血是非常罕见的事件。特定的颈部位置会使甲状腺遭受创伤，尤其是在机动车碰撞中，falls,直接打击,或体育活动。先前存在的疾病，如甲状腺肿，腺瘤，囊肿会增加出血的风险，减少腺体破裂所需的力量，使甲状腺更容易受伤。作者报告了一名53岁的男子在维护液化石油气（LPG）动力汽车时卷入火灾的案例。随后，他向急诊科就诊，右前颈部疼痛性肿胀，肿块明显。CT扫描显示右侧甲状腺出血性囊肿。工人报告说，他跳进汽车后备箱灭火，并用自己的身体盖住煤气罐喷嘴，以防止助燃剂扩散。在这种情况下,医学-法律评估有助于区分伤害的自然原因和创伤原因。医学法律评估是了解与工作相关的事件所涉及的动态的关键，以确定工人或雇主的任何法律责任。
