Intraspinal extradural synovial cysts are a rare occurrence at the spinal cord level and thus a rare cause of myelopathy. Synovial cysts usually present in the more mobile lumbar and cervical parts of the spine; however, they may also arise in the thoracic spine. We present a case of a 59-year-old male with a left upper thoracic synovial cyst at T2-3 causing disabling, progressive myelopathy, and an incomplete spinal cord injury syndrome with inability to ambulate. An urgent decompressive laminectomy with bilateral facetectomies, cyst excision, and posterior fusion was performed. Subsequently, the patient recovered full function. Synovial cysts should be considered in the differential diagnosis of progressive thoracic myelopathy. This is only the sixth reported case of a synovial cyst of this kind occurring between the levels of T1 and T7. Urgent surgical decompression is the recommended treatment.
脊髓硬膜外滑膜囊肿在脊髓水平较为罕见，因此是脊髓病的罕见病因。滑膜囊肿通常出现在脊柱活动度较大的腰段和颈段；然而，它们也可能发生在胸段脊柱。我们报告一例59岁男性，在T2 - 3水平有一个左上胸段滑膜囊肿，导致致残性、进行性脊髓病，以及不完全性脊髓损伤综合征，无法行走。实施了紧急减压性椎板切除术，包括双侧关节突切除术、囊肿切除术和后路融合术。随后，患者恢复了全部功能。在进行性胸段脊髓病的鉴别诊断中应考虑滑膜囊肿。这是仅有的第六例报道的发生在T1至T7水平之间的此类滑膜囊肿病例。推荐的治疗方法是紧急手术减压。
