Subaxial cervical XXXX : report of 35 histologically confirmed surgically treated cases and review of the literature.

@entity1 @entity12897 @entity86
STUDY DESIGN: Retrospective study OBJECTIVE: The authors' aim of the present study is to report their experience with subaxial cervical @entity12897 hoping to provide further insight into these lesions including the presenting symptoms, possible mechanisms of cyst development associated with cervical level, surgical treatments and clinical outcomes. SUMMARY OF BACKGROUND DATA: @entity12897 are relatively common in the lumbar spine and very uncommonly identified in the subaxial cervical spine. Several case reports and a few small series have been reported in the literature over the past four decades. METHODS: The authors retrospectively reviewed the cases of 35 @entity1 who underwent surgical treatment for histologically confirmed symptomatic subaxial cervical @entity12897 between 1993 and 2009. The presenting symptoms, age, sex, cervical level, operation, complications and outcomes were analyzed in this cohort. Preoperative and postoperative neurologic assessments were done by staff neurologists independent of the operating surgeon. This study was approved by the Mayo Clinic institutional review board. RESULTS: Thirty-five @entity1 underwent surgical treatment for their @entity12897 and follow-up for at least 12 months postoperatively. The mean follow-up time was 49 months (range, 12-134). There were no deaths associated with the surgery. There was one @entity86 in a @entity1 undergoing a decompressive laminectomy and posterior instrumented fusion. @entity1 outcomes were assessed using the Modified Rankin Score for 12 @entity1 was 0, 17 @entity1 was 1, 4 @entity1 was 2, and 2 @entity1 was 3. CONCLUSION: This series of 35 @entity1 with subaxial cervical @entity12897 surgically treated over a period of 17 years illustrates the relative rarity of these lesions. Magnetic resonance imaging is currently the optimal radiographic study to identify these lesions. Surgical resection can be an effective treatment.
