Review Case Reports
Long-Term Outcome of Spinal Extranodal Rosai Dorfman Disease: a Report of Two Cases and Systematic Review.
Rosai-Dorfman disease (RDD) is a rare pathologic entity caused by sinus histiocytosis with massive cervical lymphadenopathy. Isolated spinal involvement is an infrequent presentation of extranodal RDD. The clinical and radiologic appearance of RDD represents a diagnostic challenge. We report 2 patients with paraparesis caused by RDD of the thoracic spine and a PRISMA-style systematic review. ⋯ RDD is a rare occurrence and should be considered in the differential diagnosis of extradural or intradural spinal lesions. Gross total resection is recommended, and long-term clinical follow-up with MRI is advised. Residual or recurrent RDD requires steroids or radiation therapy.

Existing research about surgical start time is equivocal about associations between outcomes and late start times, and there is only one published report investigating start time in spine surgery. Therefore, the objective of this study was to assess associations between surgical start time, length of stay (LOS), and cost in lumbar spine surgery. ⋯ Late surgical start time is associated with longer LOS and higher cost in patients undergoing PLF.

To report cases of extraspinal mimics of cauda equina syndrome (CES) to enable prompt diagnosis and treatment in the future. CES results from compression of spinal nerve roots. Current practice mandates lumbosacral magnetic resonance imaging (MRI) scanning to diagnose CES. However, it may not reveal compression or provide an explanation for the presentation. We present 3 cases of suspected CES who went on to have intracranial pathology. ⋯ Negative lumbosacral MRI will not exclude extraspinal mimics of CES and, although rare, these cases should be considered.

Global neurosurgery is the practice of neurosurgery with the primary purpose of delivering timely, safe, and affordable neurosurgical care to all who need it. The aim of this study is to identify the most frequently cited articles in global neurosurgery through a bibliographic review to characterize articles and trends around this growing topic. ⋯ There is currently a deficit in both the amount of literature surrounding the topic of global neurosurgery and how much that literature is cited. Developing innovative ways to increase academic productivity within, or in collaboration with, low-middle income countries is essential to contribute to global neurosurgery.

To evaluate the surgical technique and accuracy of S2 alar-iliac (SAI) screw placement using intraoperative O-arm-based 3-dimensional navigation (O-arm). ⋯ SAI screw placement can be safely performed using the intraoperative O-arm system and our surgical technique.
