Unruptured brain arteriovenous malformations (AVM) have a heterogeneous clinical presentation, mainly related to the presence of intracerebral hemorrhage. We report the diagnosis of AVM in a patient with Parkinson's disease (PD), who undergone positron emission tomography/magnetic resonance imaging (PET/MRI) molecular brain imaging with fluorine-18-dihydroxyphenylalanine (F-DOPA). This case suggests that AVM may be occasionally recognized in molecular imaging studies using positron-emitting amino acids. Magnetic resonance imaging with susceptibility-weighted imaging (SWI) sequences and 3D time of flight (TOF) reconstruction may contribute to manage patients with AVM.

Background And Purpose: Embolization is the first-line treatment for dural arteriovenous fistulas (dAVF). The precipitating hydrophobic injectable liquid (PHIL) embolic agent is a non-adhesive copolymer with specific features and endovascular behavior. This study assessed its safety and efficacy in a prospective real-life cohort.

Background: Congenital arterial defects such as cerebral arteriovenous malformations (AVMs) increase brain bleeding risk. Conservative therapy, microsurgical removal, percutaneous embolization, stereotactic radiosurgery (SRS), or a combination may treat this serious disease. This study compares angioembolization with SRS to SRS alone in ruptured or unruptured brain ateriovenous malformations (BAVM) patients.

Wyburn-Mason disease (WMD) is a rare congenital phakomatosis known for its complex arteriovenous malformations (AVMs) predominantly affecting the brain and ocular structures. We present the case of a 19-year-old female with an unruptured Spetzler-Martin grade 5 left thalamic AVM, who initially exhibited progressive visual impairment and migraines. Following diagnosis, she was treated with trametinib, a MEK inhibitor; however, nine months later, she developed acute complications, including left monocular blindness and right hemisensory loss.

Objective: While the relationship between smoking and subarachnoid hemorrhage is well established, data regarding the probability of detecting unruptured intracranial aneurysms (UIAs) in smokers remain sparse. The aim of this systematic review and meta-analysis is to provide a comprehensive understanding of the relationship between smoking and the likelihood of identifying UIAs in healthy asymptomatic patients who underwent brain imaging for indications unrelated to UIAs.
Methods: A systematic review was conducted following the PRISMA guidelines.
