Differentiation of suprasellar xanthogranuloma (XG) from adult craniopharyngioma (CP) can be problematic in endoscopic extended transsphenoidal surgery. ⋯ Careful interpretation of preoperative magnetic resonance imaging, intraoperative endoscopic findings, and intraoperative frozen section diagnosis may be important for the differential diagnosis between XG and CP. In endoscopic-extended transsphenoidal surgery, intentional partial removal can be effective for XG after careful diagnosis.

Skull base lesions within the middle cranial fossa (MCF) remain challenging. Recent reports suggest that transorbital endoscopic approaches (TOEAs) might be particularly suitable to access the MCF and expose the lateral wall of the cavernous sinus and the Meckel's cave. ⋯ LTOEA provides a direct ventral route to the medial aspect of MCF, PA, and PCF. Although TOEAs are versatile approaches, the unfamiliar surgical anatomy and limited instrument maneuverability demand extensive cadaveric dissection before moving to the clinical setting.

The literature on neurofibromatosis (NF) has never been systematically assessed using bibliometric analytic methodologies. We quantitatively analyzed the major trends and scientific output regarding NF, highlighting potential avenues for research. ⋯ Our study exemplifies a quantitative method for understanding the historical and current state of academic efforts regarding NF. There has been a shift of treatment strategies towards targeting specific pathways involved in tumorigenesis. We highlight the top 20 genetic and molecular pathways in the literature as well as the top 20 associated syndromes. This data is encouraging as increased research in molecular targeted therapies aimed at NF pathogenesis may allow advances in disease control.

Oculomotor nerve palsy (OMNP) is a known risk in surgical management of intracranial aneurysms. The aim of this study was to determine the risk factors for surgery-induced OMNP. ⋯ This study showed that size, intraoperative rupture, and preoperative time were independent predictors of surgery-induced OMNP. Use of advanced technologies during the operation can assist in avoiding this complication.

Image-guided surgery has shown great utility in neurosurgery, especially in allowing for more accurate surgical planning and navigation. The current gold standard for image-guided neurosurgery is neuronavigation, which provides millimetric accuracy on such tasks. However, these approaches often require a complicated setup and have high cost, hindering their potential in low- and middle-income countries. The aim of this study was to develop and evaluate the performance of a mobile-based augmented reality neuronavigation solution under different conditions in a preclinical environment. ⋯ Our approach provides a viable, low-cost, easy-to-use, portable method for locating points on the scalp surface with an accuracy of 2.6 ± 1.6 mm in the best-case scenario.
