AI Article Synopsis
Article Abstract
A 66-year-old man presented with typical right trigeminal neuralgia. Neuroimaging showed a small arteriovenous malformation (AVM) in the right cerebellopontine angle. Suboccipital craniotomy verified that the AVM was almost completely embedded in the root entry zone of the trigeminal nerve and the nerve axis was tilted infero-posteriorly. The patient obtained complete pain relief without sequelae after surgery by transposition of the superior cerebellar artery and correction of the tilted nerve axis. The nidus of the unresected AVM was obliterated by gamma knife radiosurgery.

Background: Craniocervical junction dural arteriovenous fistulas (CCJ-DAVFs) are rare and complex vascular malformations that are challenging to diagnose and treat. This study aims to compare surgical and endovascular treatments for CCJ-DAVFs through a systematic review and meta-analysis.
Methods: A systematic review and meta-analysis was conducted according to the PRISMA guidelines.

Eloquent brain creates a challenge when resecting brain arteriovenous malformations (bAVMs). Here the authors present their technique of using subcortical motor mapping as an adjunct to increase safety during resection of a high-grade bAVM involving somatosensory cortex as well as cortical spinal tracts and visual tracts. After a bilateral craniotomy, they use direct cortical stimulation of the left motor cortex and subcortical stimulation using a suction stimulator to dynamically map motor tracts during the resection.

Introduction: Brain arteriovenous malformations (AVM) are complex vascular pathologies with a significant risk of hemorrhage. Stereotactic radiosurgery (SRS) is an effective treatment modality for AVM, initially popularized on the Gamma Knife (Elekta AB, Stockholm, Sweden) platform, and now benefits from the modern advances in linear accelerator (LINAC)-based platforms. This study evaluates the outcomes of LINAC-based SRS/hypofractionated stereotactic radiotherapy (hFSRT) for cerebral AVMs.

Cerebral proliferative angiopathy (CPA) is a rare subtype of cerebral arteriovenous malformation, characterized by unique angiographic features and clinical presentations. Although the clinical and angiographic characteristics of CPA have been well described, their impact on the surrounding tissues remains underexplored. Herein, we investigated the presence of calvarial thickening in patients with CPA, and discuss its potential pathogenesis.
