Sub-Saharan African experience of neurosurgical oncology care: challenges and barriers encountered at 7 cancer treatment centers.
Wide disparities in neurosurgical oncology care and treatment outcomes exist globally despite recent improvements in diagnostics and cancer therapy. To better understand the challenges to neurosurgical oncology care in low-resource settings, the authors collected data on national neurosurgical capacity and hospital diagnostic and treatment capacity across 7 national referral hospitals in 7 countries in sub-Saharan Africa (SSA). ⋯ There are significant challenges to timely and quality neurosurgical oncology care in SSA especially for children. System-level interventions are needed to strengthen neurosurgical oncology care capacity in SSA.

Surgical treatment of brain arteriovenous malformations in patients with hereditary hemorrhagic telangiectasia: a single-center experience.
Hereditary hemorrhagic telangiectasia (HHT) is an autosomal-dominant disorder characterized by multiple vascular malformations. Brain arteriovenous malformations (bAVMs) are a significant manifestation of HHT. The surgical management of these lesions in patients with HHT remains debated, with limited literature on postoperative outcomes. The goal of this study was to evaluate the safety and efficacy of surgical treatment for bAVMs in patients with HHT and propose a treatment rationale based on a single-center experience. ⋯ In this most extensive surgical series published to date, resection of bAVMs in patients with HHT showed favorable outcomes with a low complication rate, suggesting that the benefits of surgery outweigh the risks, especially considering the potential cumulative lifetime risk of hemorrhage. MR arterial spin labeling was found to be the most sensitive noninvasive measure of detecting bAVMs in patients with HHT.

Combined neuromodulation and resection for functional cortex epilepsy: a case series.
Medically refractory epilepsy (MRE) often requires resection of the seizure onset zone (SOZ) for effective treatment. However, when the SOZ is in functional cortex (FC), achieving complete and safe resection becomes difficult, due to the seizure network overlap with function. The authors aimed to assess the safety and outcomes of a combined approach involving partial resection combined with focal neuromodulation for FC refractory epilepsy. ⋯ Maximal safe resection combined with focal neuromodulation presents a promising alternative to stand-alone resections for MRE epileptogenic zones overlapping with functional brain. This combined approach prioritizes the preservation of function while improving seizure outcomes.

Characteristics of radiation-induced brain tumors: case series and systematic review.
Radiation therapy (RT) improves the outcome of patients with cancer but introduces the risk of radiation-induced neoplasms in cancer survivors. The most common radiation-induced brain tumors (RIBTs) are gliomas (RIGs), meningiomas (RIMs), and sarcomas (RISs). To investigate the characteristics of these RIBTs, the authors conducted a comprehensive review and analysis of their case series and relevant cases from the literature. ⋯ The prognosis was poor and worse for patients with RIGs and RISs than for those with RIMs, and patients with RIBTs who underwent higher-dose irradiation for primary disease had poor prognoses. Because RIBTs develop more than a decade after cranial irradiation, long-term follow-up is crucial.
