Review Meta Analysis
Safety and efficacy of laminoplasty versus laminectomy in the treatment of spinal cord tumors: a systematic review and meta-analysis.
Laminectomy (LAMT) and laminoplasty (LAMP) have been widely applied on patients with spinal cord tumors (SCTs). However, the clinical efficacy of LAMP versus LAMT remains controversial. The purpose of this study is to assess the safety and efficacy of LAMP compared to LAMT in the treatment of SCTs. ⋯ LAMP might be a safer and more effective surgical method in the treatment of SCTs. In addition, the advantage of fusion in preventing the occurrence of spinal deformity should not to be ignored. However, because of the lack of high quality randomized controlled trials and adequate data, the safety and validity of LAMP was undermined.

Review Case Reports
Treatment and survival outcomes of primary intracranial squamous cell carcinoma.
Primary intracranial squamous cell carcinoma (SCC) is a rare neoplasm associated with malignant transformation of benign epidermoid or dermoid cysts. The optimal treatment and prognosis of this rare disease are unclear. ⋯ Primary intracranial SCC shows poor prognosis, with controversial management. The results of this study indicate that complete resection of tumor when possible, followed by radiotherapy, is the optimal treatment for improving patient outcome.

Review Case Reports
Neurenteric cyst of the ventral craniocervical junction: Case report and a literature review.
Neurenteric cysts (NCs) are rare, non-neoplastic lesions arising from a failure of dissolution of the transient neurenteric canal between the foregut and the notochord. They are most frequently seen in the intradural extramedullary space in the lower cervical and upper thoracic spine. The authors describe a rare case of NC arising from the ventral cervicomedullary junction that was totally resected via a posterior approach. ⋯ NC is a rare lesion of the craniospinal junction and should be considered among differential diagnoses. Complete excision is the treatment of choice. In most instances a dorsal surgical approach will be satisfactory.

The location of the origin of the posterior inferior cerebellar artery (PICA) is highly variable. An extracranial origin PICA from the vertebral artery (VA) is not rare. But the PICA originated extradurally where the VA ascends between the transverse foramina of C-2 and C-1, a rare anatomic variant. Double-origin PICA is another rare anatomic variant observed in 1%-4% of patients in whom 2 PICA branches converge distally. ⋯ To our knowledge, this is the first report of a cadaveric anatomy case of bilateral PICA that originated extradurally between the vertebrae C-1 and C-2, and simultaneously there existed a right double-origin PICA. Such a case is rare, but understanding of the anatomic variation is important. To avoid complications during surgery at the craniovertebral junction, these potential variations should be correctly identified preoperatively.
