患者女性,30岁,因双上肢感觉障碍5年,逐渐出现双上肢、下肢无力,以至不能行走,失去劳动力。 神经系统检查:鼻唇沟对称,伸舌居中,双上下肢肌肉萎缩,肌力Ⅱ度,感觉障碍。疑诊颈,胸段脊髓病变。作X线脊髓造影检查发现T_4水平以上造影剂不能通过,一小时后作CT检查,见脊髓颈,胸段膨大,蛛网膜下腔变窄(图1),24小时后再重复作CT扫描检查,于C_4至T_4水平见一直径0.8cm囊腔为造影剂充填,脊髓外蛛网膜下腔可见环形造影剂包绕,形似靶状(图2),诊断意见:脊髓空洞症。 讨论:脊髓空洞症起病缓慢,病因不明,起病初容易被医生忽视,CT脊髓造影可扫描见脊髓内造影剂充 Female, 30 years old, with double upper extremity sensation for 5 years, double upper extremity and lower extremity weakness, unable to walk and loss of labor. Nervous system examination: symmetrical nasolabial fold, tongue middle, double upper and lower extremity muscle atrophy, muscle strength II, sensory disturbance. Suspected neck, thoracic spinal cord lesions. For X-ray myelography examination found T_4 level above the contrast agent can not pass, one hour after CT examination, see the spinal cord neck, thoracic enlargement, subarachnoid narrowing (Figure 1), 24 hours after repeated CT scan examination , A diameter of 0.8cm at C_4 to T_4 level see a cystic cavity filled with contrast agent, spinal cord subarachnoid ring can be seen around the contrast agent, the shape of the target (Figure 2), the diagnostic opinion: syringomyelia. Discussion: Syringomyelitis onset is slow, the etiology is unknown, early onset easily overlooked by the doctor, CT scintigraphy can scan the spinal cord see the contrast agent filling
