Several causes for the development of a juxtafacet cyst (JFC) of the spine have been discussed, with a focus on instability with overload of the facet joints. In the thoracic spine, JFC is a very rare space-occupying lesion, which can lead to spinal canal stenosis with pain, myelopathic signs and neurological deficits. We report a case of a 70-year-old woman who had a posterolateral fusion of L2 to S1 and, six weeks later a L1 compression fracture. In the following period a thoracolumbar kyphosis has developed. Fourteen months after the fusion procedure a left-sided JFC T11/12 was identified on MRI and CT scans which led to myelopathic symptoms. This was not seen on former MRI scans. After surgical removal of the JFC the myelopathic symptoms were clearly reduced and the woman became pain free. This case report gives a strong support to the hypothesis that spinal instability can lead to overload of the facet joints and result in JFC.
已经讨论了脊柱关节突旁囊肿（JFC）发展的几个原因，重点是关节突关节过载引起的不稳定性。在胸椎，JFC 是一种非常罕见的占位性病变，可导致椎管狭窄，出现疼痛、脊髓病体征和神经功能缺损。我们报告了一例 70 岁女性，其 L2 至 S1 进行了后路融合，六周后发生了 L1 压缩性骨折。此后出现胸腰椎后凸畸形。融合术后 14 个月，在 MRI 和 CT 扫描上发现 T11/12 左侧 JFC，导致脊髓病症状。而之前的 MRI 扫描并未发现该问题。JFC 切除术后，脊髓病症状明显减轻，患者疼痛消失。本病例报告强烈支持这样一种假设，即脊柱不稳定可导致关节突关节过载，并导致 JFC 的形成。
