This case report concerns a patient who developed reversible bilateral internuclear ophthalmoplegia as an immediate consequence of head trauma. To our knowledge, only one case of internuclear ophthalmoplegia related to head trauma has been previously reported in the literature. The mechanism by which trauma can produce a relatively isolated brain stem lesion to the medial longitudinal fasciculus is unclear. Some experimental data on the mechanisms of cerebral concussion would indicate that the biomechanical forces due to impact acceleration of the head exert their predominant effect on the posterior portion of the brain stem. This might account for critical vulnerability of the structures situated in this portion, including the medial longitudinal fasciculus.
本病例报告涉及一名因头部外伤立即出现双侧可逆性核间性眼肌麻痹的患者。据我们所知，此前文献中仅报道过一例与头部外伤相关的核间性眼肌麻痹病例。外伤导致内侧纵束相对孤立性脑干病变的机制尚不清楚。一些关于脑震荡机制的实验数据表明，头部撞击加速产生的生物力学力对脑干后部发挥主要作用。这可能解释了位于该部位的结构（包括内侧纵束）为何具有关键易损性。
