It is important to recognize the incidence and risk factors for ischemic complications after surgical revascularization for moyamoya disease (MMD). However, most studies focus on pediatric MMD or pediatric and adult MMD. Our study identified the incidence and risk factors of newly developed cerebral infarction after surgical revascularization for adult MMD. ⋯ Our findings demonstrate that newly developed, silent cerebral infarction developed more frequently than symptomatic cerebral infarction in adult patients. Cerebral infarction as initial presentation, frequent TIA before surgery, and PCA involvement were also independent risk factors for newly developed cerebral infarction after surgical revascularization for adult MMD.

Secretory meningioma (SM) is a rare histologic subtype known to cause disproportional peritumoral brain edema. Although meningiomas are defined by slow growth and mostly manifest with benign clinical symptoms, SMs can cause life-threatening deterioration. The aim of this study was to characterize the potential pitfalls in treatment of SMs by illustrating their characteristic clinical features. ⋯ Our results illustrate the complicated clinical course of this rare histologic meningioma subtype. The increased frequency of seizures may enable raised awareness of clinicians for potential complications and treatment adjustments perioperatively early at clinical admission.

The anterior lumbar spine approach has gained in popularity in recent years, but the associated access-related complications for obese patients have not been clearly established. This study aimed to analyze the relationship between obesity or overweight and the safety of the anterior lumbar spine approach. ⋯ Because BMI does not seem to increase the overall risk of complications, the anterior lumbar spine approach should be considered in obese or overweight patients, as in nonoverweight patients.

Primary leptomeningeal melanomatosis (PLM) is a rare and aggressive form of nonmetastatic invasion of leptomeninges by malignant melanocytic cells. Clinical presentation includes nonspecific meningism with various forms of cerebrospinal fluid circulation or absorption disorders leading to hydrocephalus. ⋯ To the best of our knowledge, this is the first report of an amelanotic form of PLM without association of neurocutaneous melanosis in a child. This case report illustrates the difficulty of diagnosis in the absence of cutaneous lesions and lack of melanin.

Endoscopic endonasal skull base surgery has become widely accepted in neurosurgery and otolaryngology over the last 15 years. However, there has yet to be a formal curation of the most impactful articles for an introductory curriculum to its technical evolution. ⋯ Identification of the most cited works within endoscopic endonasal skull base surgery shows greater anatomic access and safety over the last 2 decades. These articles can serve as an educational tool for novices or midlevel practitioners wishing to obtain a greater understanding of the field.
