脊髓脂肪瘤是指与脊髓明显相连并可附着于脊膜的脂肪及结缔组织团块。病因为神经和椎管在胚胎形成时的错构和退行性变。多累及脊髓圆锥和终丝,压迫和缩窄脊髓而产生症状。临床上可分为:髓内脂肪瘤、脂肪脊髓脊膜膨出和终丝脂肪瘤三种类型。有关该瘤的治疗尚有争论,主要是多数病人出生时并无症状。而出现症状者随年令增长而增多,以致出现不可逆的神经和泌尿系统功能障碍。少数病人则始终无症状。作者报告了激光切除脂肪瘤50例,对手术的利弊进行了讨论。50例中男21例,女29例。年令均在19岁以下。其中23例术前检查神经和泌尿系统功能正常。余27例有症状者为运动障碍和尿失禁者10例,单独运动障碍者10例,单独尿失禁者7例。所有病人均经脊髓造影,非增强CT 和脊髓CT 明确诊断,并分为三组:A 组18例,皆为1岁以下婴儿,平 Spinal lipomas are fat and connective tissue masses that are clearly attached to the spinal cord and can attach to the meninges. The disease is due to the misconfiguration and degeneration of the nerves and spinal canal during embryonic development. More involved spinal cord conusions and terminal wires, compressing and narrowing the spinal cord to produce symptoms. Clinically, it can be divided into three types: intramedullary lipoma, lipo-myelomenomyocele, and terminal-line lipoma. There is controversy regarding the treatment of this tumor, mainly because most patients are asymptomatic at birth. Symptoms increase with annual growth, resulting in irreversible neurological and urinary dysfunction. A small number of patients are always asymptomatic. The authors reported 50 cases of laser ablation of lipomas and discussed the advantages and disadvantages of surgery. In 50 cases, there were 21 males and 29 females. The annual orders are all under 19 years old. Among them, 23 cases had normal preoperative nerve and urinary system tests. Of the 27 patients with symptoms, 10 were dyskinesia and urinary incontinence, 10 with dyskinesia alone, and 7 with urinary incontinence alone. All patients were diagnosed by myelography, non-enhanced CT, and spinal cord CT. They were divided into three groups: 18 patients in group A, all of whom were under 1 year old.
