Case Reports
Hemorrhagic Atypical Planum Sphenoidale Meningioma with Intermittent Vision Loss-A Rare Presentation of Apoplexy.
Symptoms that mimic pituitary apoplexy may be encountered with other neoplastic or infectious lesions. ⋯ As the most common benign intracranial tumors, meningiomas should remain in the differential for patients presenting with apoplectiform symptoms.

Multicenter Study
Prognostic Discrepancy on Overall Survival Between Ambulatory and Non-ambulatory Patients with Metastatic Spinal Cord Compression (MSCC).
Contradictory results have been reported regarding the prognostic effect of ambulatory status in patients with metastatic spinal cord compression (MSCC). The aim of this study was to investigate whether ambulatory status is a significant predictor of overall survival in patients with MSCC and to distinguish the differences of predictors between patients who were ambulatory and those who were not ambulatory before operation. ⋯ Ambulatory status was not shown to predict the prognosis of patients with MSCC. prognostic factors should be distinguished between ambulatory and nonambulatory patients when choosing a therapeutic modality.

Hemimetameric segmental shift (HMMS) is defined as ≥2 contralateral hemivertebrae (HV) that are separated by at least 1 normal vertebra. Theoretically, the 2 HV tend to balance each other to produce minor spine deformities. However, curve progression has still been observed in HMMS. No research has yet specifically studied its surgical treatment. This study aimed to report efficacy of HV resection for HMMS. ⋯ HV resection is a safe and effective treatment for HMMS that causes progressive or severe deformity.

To determine if there is a difference in reoperation rates for symptomatic nonunions in atlantoaxial (C1-C2) fusions with or without bone morphogenetic protein (BMP) using data from a national spine registry and to analyze the different types of bone grafts used in the non-BMP group. ⋯ Using one of the largest retrospective studies on C1-C2 fusions with and without BMP, we found no difference in reoperation rates for symptomatic nonunions. For the non-BMP group, we found that lamina (+/- allograft) or allograft alone may also be just as effective as iliac crest graft (+/- allograft) in having no reoperations for symptomatic nonunions.

Interhospital transfers for endovascular thrombectomy (EVT) evaluation have increased since the publication of landmark neuroendovascular stroke trials in 2015. The lack of guidelines to select potential EVT candidates prior to transfer can lead to instances where, despite considerable costs and transport risks, transferred patients do not ultimately undergo EVT. Our aim was to characterize the patterns and identify predictors for EVT on transfer. ⋯ A higher collateral score, the acquisition of CTA imaging at the referring centers, and a higher NIHSS score independently predicted EVT on transfer.
