Purpose: Surgical stabilization of the Atlas vertebrae is indicated for severe atlantoaxial instability (AAI) in patients with Down syndrome (DS). This study aims to evaluate the morphological characteristics of the Atlas lateral mass (ALM) in patients with DS with regard to safe instrumentation for surgical stabilization and to compare them with non-syndromic group.
Methods: This multicenter, retrospective, case-control study included age- and sex-matched patients with and without DS aged > 7 years with a cervical computed tomography (CT) scan.
Objectives At present, the literature lacks data on the outcome of neurosurgery training programs in the Middle East. In this study we aim to assess the attrition, completion of training and success rates in the Saudi Board of Neurosurgery (SBNS). Methods A cohort of 115 trainees who started SBNS training during 2001-2014 was reviewed.
View Article and Find Full Text PDFLeptomeningeal cysts, which are cystic collections filled with cerebrospinal fluid, are rare complications following pediatric head trauma and surgical correction of craniosynostosis. These cysts develop due to cerebrospinal fluid pulsations and brain growth that cause expansion of the dural tears. Although primary repair of the dural defect is the definitive treatment, the risk of cyst recurrence remains.

Study Design: This was an interventional human cadaver study and radiological study.
Objectives: Atlas instrumentation is frequently involved in fusion procedures involving the craniocervical junction area. Identification of the entry point at the center of atlas lateral mass (ALM) is challenging because of its rounded posterior surface and the surrounding venous plexus.
Atypical teratoid/rhabdoid tumor (AT/RT) is a highly malignant central nervous system neoplasm usually diagnosed in young children, although it can occur in adults. Prognosis for AT/RT is poor, with a median survival of 10 - 11 months. We report a rare case of adult sellar and suprasellar AT/RT in a 36-year-old female patient.
