We present a patient with a relatively rare condition: Charcot joint of the shoulder, with a rare complication, the first known example of combined neurovascular compression in this location. A 49-year-old man presented with neuropathic arthropathy of the shoulder caused by syringomyelia from a Chiari I malformation, leading to compression of both the brachial plexus and the axillary vein by mass effect from the synovitis. The brachial plexopathy resolved with surgical decompression and synovectomy, and the syringomyelia stabilized after Chiari decompression. A large acromioclavicular joint synovial cyst developed as a late complication, which was treated nonoperatively. Understanding neuropathic arthropathy can explain the spectrum of interrelated typical and atypical features in this case over long-term follow-up.
肩部夏科关节，伴有罕见的并发症，这是该部位首例已知的神经血管压迫合并症。一位 49 岁男性因小脑扁桃体下疝畸形引起的脊髓空洞症导致肩神经病变性关节炎，导致滑膜炎症的肿块效应压迫臂丛神经和腋静脉。臂丛神经病通过手术减压和滑膜切除得到缓解，脊髓空洞症在小脑扁桃体减压后稳定下来。作为晚期并发症，出现了一个大的肩锁关节滑膜囊肿，采用非手术治疗。了解神经病变性关节炎可以解释该病例在长期随访中的一系列相关的典型和非典型特征。
