Surgical Intervention is Associated with Improved Outcomes in Patients with Symptomatic Cervical Spine Tarlov Cysts: Results from a Prospective Cohort Study.

Background: Tarlov cysts are known contributors to radiculopathy but are often misdiagnosed and mismanaged due to a paucity of information. This is particularly true of cervical spine Tarlov cysts because most attention has been focused on sacral cysts. In this study, we describe our longitudinal experience with patients who underwent surgery for cervical spine Tarlov cysts. We hypothesized that patients undergoing surgical treatment for cervical spine Tarlov cysts would report improvement following surgery.
Methods: We conducted a prospective study of patients who underwent surgical treatment for cervical Tarlov cysts between 2010 and 2021. The Short-Form 36-item survey (SF-36) was administered at the preoperative and follow-up visits. Repeated measures analyses were used to assess changes from preoperatively to postoperatively.
Results: A total of 37 patients with cervical spine cysts were included in the study. Follow-up data were available for 27 patients with a median follow-up of 1 year. Of the cohort, 97.3% were women, with an average age of 47.5 ± 10.3 years. Patients reported statistically significant improvement in 2 of the 4 SF-36 physical health domains (physical function, P< 0.001; and bodily pain, P < 0.001) and 2 of the 4 mental health domains (vitality/energy, P < 0.003; and social functioning, P = 0.007). Patients also reported less interference in work, education, and retirement activities at follow-up (P = 0.017).
Conclusions: Our longitudinal series consisted of patients with symptomatic cervical spine Tarlov cysts, which, to the best of our knowledge, is the largest series described. Significant improvements in the SF-36 domains were documented, indicating these patients can be successfully treated surgically.
