Review Meta Analysis Comparative Study
Comparision of results between posterior fossa decompression with and without duraplasty for the surgical treatment of Chiari malformation Type I：a systematic review and meta-analysis.
Posterior fossa decompression without (PFD) or with duraplasty (PFDD) for the treatment of type 1 Chiari malformation (CM-1) is controversial. We thus performed a systematic review and meta-analysis of studies to assess the effect on clinical and imaging improvement, operative time, complications, and recurrence rate between PFD and PFDD in patients with CM-1. ⋯ PFDD can be an optimal surgical strategy because of its higher clinical improvement and lower recurrence rate in the patients with syringomyelia. In patients without syringomyelia, PFD can be a preferred choice because of its similar clinical improvement and lower costs. Future randomized studies with large numbers and the power to provide illumination for surgical decision making in CM-1 are warranted.

Review Meta Analysis
Epidural steroids at closure post-microdiscectomy/laminectomy for reduction of post-operative analgesia: systematic review and meta-analysis.
This review assessed the efficacy of epidural steroid administration on the reduction of pain, hospital stay time, and use of opioid analgesics postoperatively. ⋯ Intraoperative or perioperative epidural administration of steroids offers significant benefits in terms of pain control, reduction in LOS, and use of postoperative opioid analgesia. Before steroids are routinely used by spinal surgeons, however, significantly more research is required. A particular emphasis should be placed on quality study protocols and data recording, to allow for more thorough analyses in the future.

Review Case Reports
Unilateral Symptomatic Hypertrophic Olivary Degeneration Secondary to Midline Brainstem Cavernous Angioma: A Case Report and Review of the Literature.
Hypertrophic olivary degeneration (HOD) is a rare phenomenon in the dento-rubro-olivary pathway caused by lesion or disruption of the fibers of the Guillain-Mollaret triangle. Hemorrhage of pontine and midbrain cavernous angiomas can rarely lead to HOD portending neurologic deterioration and possible concomitant life-threatening complications; for this reason, it may define a poignant consideration in planning intervention. ⋯ The literature regarding imaging recommendations for stable cavernous angioma in the midbrain-pontine junction is reviewed. The implication of HOD for patient outcome is discussed and a comment is made on how the development of HOD may affect management of the cavernous angioma.

Review Case Reports
Presacral Tarlov cyst as an unusual cause of abdominal pain: new cases and literature review.
A presacral Tarlov cyst is an unusual cause of abdominal pain. The unusual location of a presacral Tarlov cyst can lead to misdiagnosis and inappropriate treatment. To guide appropriate diagnosis and treatment, we reviewed causes, clinical presentations, radiologic features, and management options of this extremely rare lesion. ⋯ Although extremely rare, presacral Tarlov cysts should be suspected in patients with abdominal pain, especially when pain occurs along with other neurologic symptoms. This review provides a systematic description of this rare disease, which may be helpful in guiding the appropriate diagnosis and treatment.

Review Case Reports
Atlantooccipital Rotatory Dislocation: A Case Report and Systematic Review.
Atlanto-occipital rotatory dislocation (AORD) has rarely been reported in the literature; for this reason, the clinicoradiologic characteristics of this injury are not well described. ⋯ Compared with previously classified atlanto-occipital dislocations, AORD is an independent and unique variation. AORD presents with different biomechanical, clinicoradiologic, and prognostic characteristics and represents an important addition to the spectrum of atlanto-occipital dislocation injuries.
