Chiari I malformation is often seen in children and may be asymptomatic. Acute neurological injury following trauma in children with Chiari I malformation has been reported in literature. Traumatic contusion involving the cerebellar tonsils is rarely described in children and usually occurs in patients with Chiari I malformation/cerebellar tonsillar ectopia. It is unknown if activity restriction should be advised in children with asymptomatic Chiari I malformation given the potential for this injury. We describe a case of cerebellar tonsillar contusion in a child with concomitant skull vault fracture and review the literature for similar cases. We also propose a plausible mechanism to explain tonsillar contusion in patients with Chiari I malformation.
Chiari I型畸形常见于儿童，可能无症状。文献报道过Chiari I型畸形儿童外伤后出现急性神经损伤。儿童创伤性挫伤累及小脑扁桃体的情况鲜有描述，通常发生于Chiari I型畸形/小脑扁桃体异位患者。鉴于有这种损伤的可能性，对于无症状Chiari I型畸形儿童是否应建议限制活动尚不清楚。我们描述了1例伴有颅骨穹窿骨折的儿童小脑扁桃体挫伤病例，并回顾了类似病例的文献。我们还提出了一个合理的机制来解释Chiari I型畸形患者的扁桃体挫伤。
