PURPOSE
To describe a percutaneous CT-guided method for drainage of perineurial (Tarlov) cysts, which are a cause of sciatica and low back pain, and to report the prevalence of these cysts within the population as detected by MR.
METHODS
Five hundred sequential lumbosacral spine MRs were evaluated for the presence of a perineurial cyst. Using CT-guided percutaneous drainage techniques, seven cysts were drained in five symptomatic patients.
RESULTS
Of the 500 sequential lumbosacral spine MRs, examinations from 23 patients showed perineurial cysts, a prevalence of 4.6%. Five patients (1%) were symptomatic from the cysts. After CT-guided percutaneous drainage, instant pain relief lasted from 3 weeks to 6 months without the risk or cost of spine surgery.
CONCLUSIONS
Lumbosacral perineurial cysts are common lesions that are usually asymptomatic but may cause pressure symptoms. Cyst puncture can alleviate the pain. Although the cysts repressurized and the patients' symptoms returned in most cases, this technique seems to be a quick and simple way of at least attaining a pain-free interval and possibly a complete cure as occurred in one patient in this study.
目的
描述一种经皮CT引导下引流神经束膜（塔尔洛夫）囊肿的方法，该囊肿是坐骨神经痛和腰痛的病因之一，并报告通过磁共振成像（MR）检测到的这些囊肿在人群中的患病率。
方法
对500例连续的腰骶部脊柱MR检查评估是否存在神经束膜囊肿。采用CT引导下经皮引流技术，对5例有症状的患者的7个囊肿进行了引流。
结果
在500例连续的腰骶部脊柱MR检查中，23例患者的检查显示存在神经束膜囊肿，患病率为4.6%。5例患者（1%）因囊肿出现症状。经CT引导下经皮引流后，即时疼痛缓解持续3周至6个月，无脊柱手术的风险或费用。
结论
腰骶部神经束膜囊肿是常见病变，通常无症状，但可能引起压迫症状。囊肿穿刺可缓解疼痛。尽管在大多数情况下囊肿会再次增压且患者症状复发，但该技术似乎是一种快速简单的方法，至少能实现无痛期，甚至可能如本研究中的1例患者那样完全治愈。
