A 17-year-old male presented with thoracic myelopathy 12 months after a stab injury to the thoracic spine. The patient reported that symptoms and signs had gradually worsened in the 3 months prior to his examination. Magnetic resonance imaging depicted not only an extradural arachnoid cyst but severe spinal cord compression. The cerebrospinal fluid pressure and dynamics associated with herniation of the spinal cord resulted in the formation and enlargement of an extradural arachnoid cyst. The pressure effect of the cyst accounted for the thoracic myelopathy.
一名17岁男性在胸椎刺伤12个月后出现胸段脊髓病。患者报告称，在检查前3个月，症状和体征逐渐加重。磁共振成像不仅显示硬膜外蛛网膜囊肿，还显示严重的脊髓受压。脑脊液压力及脊髓疝出的动力学变化导致硬膜外蛛网膜囊肿形成并扩大。囊肿的压迫作用导致了胸段脊髓病。
