Anterior inferior cerebellar artery (AICA) trunk aneurysms are rare entities. Given the eloquence of the AICA in supplying the cerebellum and brainstem, in theory, sacrifice or occlusion of the a1-a2 segment in lesions involving the AICA may lead to various complications. However, some patients might experience no complication or favorable recovery. ⋯ The prognosis was associated with collateral circulation of the AICA, and collateral circulation was discussed. In case of an a1-a2 aneurysm that is hard to occlude without sacrificing the parent artery, careful hemodynamic and morphologic evaluation for collateral flow is warranted. If collateral flow is demonstrated or the aneurysm is flow-related with cerebellar arteriovenous malformation, PAO of the a1-a2 segment can be an acceptable option.

Piezosurgery (PS) has gained increasing dispersion in neurosurgery. In pediatric neurosurgery, the experience is limited to craniosynostosis surgery. The present study assesses PS in the pediatric population, also considering outcomes and complications in cranial and spinal procedures. ⋯ PS is a safe and effective tool that can be specifically recommended for bone splitting and graft, laminotomy, and craniotomy in cosmetically eloquent areas. The limit of operation times can be overcome by a learning curve in neurosurgery and PSP.

The predominant neurosurgical approach to medication-refractory essential tremor is thalamic deep brain stimulation (DBS). The emergence of magnetic resonance-guided focused ultrasound (MRgFUS) thalamotomy has reawakened the debate surrounding the use of DBS versus thalamotomy for this indication. Herein, we aimed to provide a contemporary comparison between DBS and MRgFUS. ⋯ In context of prior literature, both DBS and MRgFUS significantly improve tremor control and QoL. The 2 approaches are predominantly differentiated by their AE-profile. Additional head-to-head comparison on matched clinical populations are required to more accurately compare clinical efficacy and long-term outcomes.

Review Case Reports
Occult transorbital intracranial injury by a windscreen wiper handle: a case report and review of the literature.
We present the case of a 51-year-old male with an occult transorbital intracranial injury after a car accident. The identified foreign object was a windshield wiper handle. To our knowledge, this is the first case reported. ⋯ Occult TII is a rare subtype of penetrating brain injury. Diagnosis requires high suspicion as it can be missed during physical examination. Computed tomography (CT) scan, CT angiogram, and magnetic resonance imaging should be performed in order to design the optimal treatment for each patient. Magnetic resonance imaging should be avoided when metallic density on CT is observed. The use of a broad-spectrum antibiotic regimen is critical.

Many controversies exist in the diagnosis and management of this aggressively malignant condition, mainly because of limited literature and lack of randomized control trials, resulting in nonstandardized treatment methods. We performed a comprehensive review of the literature to identify management approach and treatment options for esthesioneuroblastoma. ⋯ Surgical resection followed by radiotherapy is the standard for treatment for higher-grade lesions. The endoscopic endonasal approach is gaining further recognition with more favorable outcomes and better survival than for open surgery. Postoperative radiotherapy is associated with the highest overall survival and shows benefit for patients with higher-stage disease and those who receive chemotherapy. Recurrence rates after treatment vary drastically in the literature and, therefore, prolonged follow-up with repeated imaging is recommended. Lifelong surveillance is recommended because of late recurrences associated with this tumor.
