INTRODUCTION
Isolated oculomotor nerve palsy after mild traumatic brain injury is unusual and prognostically significant due to unclear mechanisms and recovery challenges. We present a case of isolated oculomotor nerve palsy following minor head trauma, shedding light on this unusual occurrence.
CASE REPORT
A 24-year-old male experienced severe vision loss and right-sided oculomotor nerve palsy after a motor vehicle collision. Initial imaging showed a hemorrhagic focus in the left posterior fossa and a contusion in the corpus callosum, yet no direct cause for the nerve palsy was found. Partial recovery was observed after 12 months.
CONCLUSION
This case underscores the importance of maintaining a heightened suspicion for occult intracranial findings, especially when the initial non-contrast computed tomography was inconclusive. Timely clinical assessment and appropriate radiological investigations by emergency physicians are crucial for improving the prognosis.
引言
轻度创伤性脑损伤后孤立性动眼神经麻痹并不常见，由于其机制不明且恢复存在挑战，因此具有重要的预后意义。我们报告一例轻度头部外伤后孤立性动眼神经麻痹的病例，以阐明这一不寻常的情况。
病例报告
一名24岁男性在机动车碰撞后出现严重视力丧失和右侧动眼神经麻痹。初始影像学检查显示左后颅窝有一个出血灶，胼胝体有挫伤，但未发现导致神经麻痹的直接原因。12个月后观察到部分恢复。
结论
该病例强调了对隐匿性颅内病变保持高度怀疑的重要性，尤其是当初始非增强计算机断层扫描结果不明确时。急诊医生及时的临床评估和适当的影像学检查对于改善预后至关重要。
