As one subtype of meningiomas, chordoid meningiomas (CMs) are rarely described. In this study, the authors aimed to analyze the incidence, clinical features, treatment, and prognostic factors of CMs. ⋯ CM is a rare subtype of World Health Organization grade II meningioma. It more frequently involved the adult patients and was without sex predilection. The confirmed diagnosis relied on pathological validation. Total resection whenever possible is recommended to prolong PFS of patients. The value of adjuvant radiotherapy for CM need to be further studied.

There is a paucity of available strategies to increase visibility and engagement in social media (SM) within the neurosurgical community. The objective of this study was to investigate the possible factors for engagement and reach among SM users in neurosurgery. ⋯ The current study demonstrates that our SM users predominantly comprise a younger demographic and that content optimization with media materials may lead to higher visibility and engagement. The impact of high SM reach on academic neurosurgical programs remains to be determined.

Disposal of occipital condyle in the far lateral approach for ventrolateral foramen magnum meningiomas.
To investigate the necessity of drilling the occipital condyle in a tailored far lateral approach for resection of ventrolateral foramen magnum meningiomas (FMMs). ⋯ The surgical approach for ventrolateral FMMs varies depending on the location of dural attachment with reference to VA dural entry. Bone removal is warranted in FMMs arising from both sides of the VA to allow superolateral displacement of the VA to some extent, improving surgical accessibility to the hidden VA auxiliary space and achieving a more radical tumor resection. It should be a reasonable alternative to the conventional aggressive VA transposition in cases of ventrolateral FMMs.

The brainstem comprises a large variety of fiber tracts and nerve nuclei and is unarguably one of the most crucial parts of the brain. Reliable noninvasive visualization of its anatomy may help relate normal and pathological anatomic variations to neurologic/psychiatric disorders. In this study, we explored the potential of direction-encoded track-density imaging (TDI) for depicting the intricate anatomy of the brainstem. ⋯ TDI images provide optimal delineation of nerve nuclei and fibers in the upper brainstem, but have more difficulty identifying more caudal structures.

The nasoseptal flap (NSF) has been shown to be a mainstay in the reconstruction of skull base defects. We evaluated the efficacy and complications of NSF in patients with a history of septal surgery who had the potential risk of tearing and poor vascularity. ⋯ There was no difference in rate of CSF leakage or flap integrity between the 2 groups. Therefore, NSF for skull base reconstruction is feasible in patients with a history of septal surgery.
