A 21-year-old woman, who had undergone foramen magnum decompression for her symptomatic Chiari malformation (Type 1) 7 years before, presented with recurrence of the symptoms. Neuroradiological examinations demonstrated regeneration of the foramen magnum that was caused by new bone formation, as confirmed at the second surgery. Neurological improvement was obtained after the removal of the regenerated foramen magnum. This observation, though rare, deserves to be kept in mind during the postoperative follow-up period in young patients with Chiari malformation.
一名21岁女性，7年前因症状性Chiari畸形（1型）接受了枕骨大孔减压术，现症状复发。神经放射学检查显示枕骨大孔再生，系新骨形成所致，二次手术证实了这一点。切除再生的枕骨大孔后神经功能得到改善。这一观察结果虽罕见，但在Chiari畸形年轻患者的术后随访期间值得牢记。
