| 目的 探讨神经根鞘囊肿在连续颈椎MRI检查中的发病率和发病特点。方法 回顾性分析安徽省二院南区2021~2022年1 237例行颈椎MRI检查者中被诊断为神经根鞘囊肿(NRSC)的51例患者临床资料,计算NRSC的总发病率及男女发病率差异;计算单发与多发患者构成比、多发患者中病灶对称与不对称分布的构成比;计算病灶在左右侧、颈胸段椎间隙中的分布构成比及其差异;对NRSC患者的C3/4~T2/3椎间盘退变程度按改良Pfirrmann分级进行评分,分析患者病灶数量与年龄及椎间盘退变程度之间的相关性。结果 本院区颈椎MRI检查者中,NRSC发病率为4.1%,男女发病率分别为2.0%、5.4%,差异有统计学意义(P<0.05);51例患者中,单发与多发构成比之间差异不显著(P=0.327);多发病例中,对称发生的病灶构成比(66.7%)与不对称者(33.3%)差异有统计学意义(P<0.05);病灶在左右侧构成比差异无统计学意义(P=0.783),在C6/7(28.8%)、C7/T1(31.4%)、T1/2(26.3%)椎间隙的构成比高于其它椎间隙。患者的病灶数量与年龄、颈椎间盘退变程度无相关性(r=0.184、-0.002,P均>0.05)。结论 NRSC在安徽省二院南区连续颈椎MRI检查中发病率为4.1%,女性多见;病灶可单发或多发(多呈对称性),好发于C6/7、C7/T1、T1/2椎间隙;患者年龄大小或颈椎间盘退变程度不影响患者的病灶发生数量。 |

| Objective To investigate the incidence and characteristics of nerve root sheath cyst in continuous MRI examination of cervical spine.Methods The clinical data of 51 cases diagnosed with nerve root sheath cyst(NRSC) among 1 237 patients who underwent cervical MRI from 2021 to 2022 in Anhui No.2 Provincial People's Hospital were retrospectively analyzed, and the total incidence of NRSC and the difference between male and female incidence were calculated. The proportion of single and multiple patients and the proportion of symmetrical and asymmetric distribution of lesions in multiple patients were calculated. The distribution and composition ratio of lesions in the left and right side, cervical and thoracic intervertebral space and their differences were calculated. The degree of C3/4~T2/3 disc degeneration in NRSC cases was scored according to the modified Pfirrmann scale, and the correlation between the number of lesions and age and the degree of disc degeneration was analyzed.Results The incidence of NRSC was 4.1% in patients with cervical spine MRI in our hospital, and the incidence of NRSC was 2.0% and 5.4% in men and women, respectively, with statistical significance(P< 0.05). There was no significant difference between single and multiple component ratio in 51 patients(P=0.327). In multiple cases, the proportion of symmetrical lesions(66.7%) was significantly different from that of asymmetric lesions(33.3%)(P < 0.05). There was no significant difference in the composition ratio of lesions on the left and right side(P=0.783), but the composition ratio of lesions in the C6/7(28.8%), C7/T1(31.4%) and T1/2(26.3%) intervertebral spaces was higher than that in other intervertebral spaces. The number of lesions was not correlated with age or degree of cervical disc degeneration(r=0.184,-0.002,P>0.05).Conclusions The incidence of NRSC is 4.1% in continuous cervical MRI examination in the Anhui No.2Provincial People's Hospital, and it is more common in women. Lesions can be single or multiple(mostly symmetrical), preferably in the C6/7,C7/T1, T1/2 intervertebral space. Age or degree of cervical disc degeneration does not affect the number of lesions. |
