An unusual case of Type I Chiari malformation that became symptomatic after closed head injury is reported. The patient manifested transient upper extremity weakness, persistent lower cranial nerve dysfunction, and cerebellar signs that slowly resolved. Magnetic resonance images showed tonsillar ectopia but no displacement of the brain stem or syringomyelia. Type I Chiari malformation should be included in the differential diagnosis of patients who present with upper extremity weakness, lower cranial nerve palsies, or cerebellar signs after trauma.
报告了一例不寻常的I型Chiari畸形病例，该病例在闭合性头部损伤后出现症状。患者表现为短暂的上肢无力、持续的低位颅神经功能障碍以及逐渐缓解的小脑体征。磁共振成像显示扁桃体异位，但脑干无移位或脊髓空洞症。对于外伤后出现上肢无力、低位颅神经麻痹或小脑体征的患者，鉴别诊断应包括I型Chiari畸形。
