患者,男性,18岁,因双下肢麻木,行走无力3个月,不能行走7天于1990年4月25日入院,体检发现,T_6 以下各种感觉减退,腹壁、提睾反射减弱,双下肢肌力Ⅲ级,肌张力低下,轻度肌萎缩。跟、膝腱反射减弱。入院后半个月,感觉平面上升至T_2、T_3,双下肢肌力“0”级。行L_(3.4)与L_(4.5)椎间隙穿刺,未抽出脑脊液,于L_(2.3)椎间隙穿刺:脑脊液压力0.43Kpa,色深黄,置试管内迅速凝固。白细胞数正常,蛋白1.Og/L。行上行性椎管造影显示:L_3与T_(10)平面完全梗阻。小脑延髓池穿刺造影显示:T_1平面完全梗阻。1990年5月10日在全麻下行C_7～T_(10)椎管探查(中间留一椎板未切),见硬脊膜张力高,无搏动。切开硬膜见肿瘤特长,位于脊髓背侧,呈灰褐色,边界不清;下至T_(10)以下(由于切口所限,未探及肿瘤 Patient, male, 18 years old, numbness of both lower extremities, walking weakness 3 months, unable to walk 7 days in April 25, 1990 admitted to the hospital, physical examination found that below T_6 various sensory decline, abdomen, cremasteric reflex decreased, Muscle power level Ⅲ, low muscle tone, mild muscle atrophy. With, knee tendon reflexes weakened. Half a month after admission, feeling flat to T_2, T_3, lower extremity muscle strength “0” level. In L_ (3.4) and L_ (4.5) intervertebral space punctures, cerebrospinal fluid (CSF) was not extracted. The puncture of L_ (2.3) intervertebral space was performed. The pressure of cerebrospinal fluid was 0.43Kpa. Normal number of white blood cells, protein 1.Og / L. The line of upstream spinal angiography showed: complete obstruction of L_3 and T_ (10) planes. Cerebellar cistern puncture angiography showed: T_1 plane complete obstruction. May 10, 1990 under general anesthesia C_7 ~ T_ (10) spinal exploration (leaving a lamina in the middle not cut), see the high dural tension, no beating. Cut the dura mater to see the tumor characteristics, located in the dorsal spinal cord, was brown, the border is unclear; down to T_ (10) or less (due to incision limits, no exploration and tumor
