Supratentorial neurenteric cyst—A case report

Supratentorial neurenteric cyst is a rare congenital lesion. We report here a case of a 33-year-old female who presented with seizures. A multicystic lesion in the left premotor cortex with moderate contrast enhancement was demonstrated with MRI. Microscopically, the lesion showed small cystic structures filled with a proteinaceous fluid. The wall of the cysts was lined with a single layer of ciliated columnar or cuboidal epithelium on a basement membrane. Glandular structures resembling gastrointestinal glands were also present. The cells of the cyst lining and glandular structures revealed strongly positive immunoreactions for epithelial markers (cytokeratin and epithelial membrane antigen).     

人工颈椎间盘置换术治疗脊髓型颈椎病的疗效观察

目的 观察应用人工颈椎间盘置换术治疗脊髓型颈椎病的疗效.方法对20例脊髓型颈椎病患者24个椎间盘行Prestige LP人工颈椎间盘置换术.术后以Odom分级标准评价疗效,以JOA评分评价脊髓功能,以VAS评分评价颈、肩部及上肢疼痛情况.X线片测量假体椎间盘间隙角及颈椎过屈、过神位活动度,观察异位骨化、骨赘形成及假体松动等情况.结果 患者均获随访,时间30～48个月.患者神经功能均恢复满意.Odom分级评分：优18例,良2例.脊髓功能JOA评分与术前比较差异有统计学意义（P〈0.05）,颈、肩部及上肢VAS评分与术前比较差异均有统计学意义（P〈0.05）.假体活动度与上、下位相邻节段的活动度比较差异均无统计学意义（P〉0.05）.1例单节段于术后24个月发生异位骨化.未见假体移位、松动、下沉等并发症.结论 颈椎人工椎间盘置换患者术后恢复快,颈椎稳定性和活动度无明显受损,近期疗效满意.
