Pseudomeningocele is a well known complication of foramen magnum decompression. Symptomatic subdural hygroma has not previously been described. We discuss a case of Arnold Chiari malformation type 1 in a 55-year-old Caucasian woman who underwent foramen magnum and upper cervical decompression and who developed a symptomatic subdural hygroma 2 weeks following surgery. This complication was most likely due to a technical error during surgery. It responded favourably to conservative therapy.
假性脑脊膜膨出是枕骨大孔减压术一种众所周知的并发症。有症状的硬脑膜下积液此前尚未见报道。我们讨论了一例55岁白种女性的1型阿诺德-奇阿利畸形病例，该患者接受了枕骨大孔及上颈椎减压术，术后2周出现有症状的硬脑膜下积液。这种并发症很可能是手术过程中的技术失误所致。它对保守治疗反应良好。
