Background: Gliomas are diffuse intra-axial lesions, which can be accessed by multiple surgical corridors for a same location depending on the surgeon's preference. 5-Aminolevulinic Acid use facilitates the extend of resection in case of high-grade gliomas, especially when differentiating normal brain from tumor periphery is challenging. Methods:...

Background Spontaneous obliteration of cerebral arteriovenous malformations (AVMs) is a rare phenomenon. Hereditary Hemorrhagic Telangiectasia (HHT) is a predisposal genetic condition for AVMs development in all organs. Case illustration We report the case of a 34 years old woman with HHT family history. After radiosurgical treatment of a symptoma...

WHO grade II progestin-related meningiomas have been reported in recent series but we found no previous study describing their long-term outcome. Our study aimed to evaluate patients operated on for high-grade intracranial meningioma and who underwent long-term exposure to high dose of cyproterone acetate, nomegestrol acetate, and chlormadinone ace...

Objective Our study aimed to identify predictive factors for malignant post-treatment edema and hemorrhage in patients who underwent microsurgical treatment of arteriovenous malformation (AVM) in our institution. Methods The study included 72 patients treated by microsurgery for cerebral symptomatic and/or ruptured AVM between 2010 and 2020. Six p...

Our study aimed to evaluate the outcome of patients with ruptured blood-blister like aneurysm (BBLA) in our institution by comparing microsurgical selective treatment to endovascular treatment using flow-diverter stent (FD). Our study included 18 consecutive patients treated for BBLA between 2004 and 2020. Until 2014, microsurgery was preferred in...

Introduction: The relationship between meningioma and progestins has not been elucidated. Meningioma regression after acetate cyproterone (CA) withdrawal has been reported. Our purpose was to evaluate the meningioma evolution after withdrawal of progestins in patients who underwent long-term exposure to CA, nomegestrol acetate (NA), chlormadinone...

Introduction: High grade progestin related meningiomas have been reported in recent series but we found no previous study describing their long-term outcome. Our study aimed to evaluate patients operated on for high grade intracranial meningioma and who underwent long term exposure to high dose of cyproterone acetate, nomegestrol acetate and chlorm...

Background/objectives The present study aimed at evaluating the impact on the early outcome of patients with ruptured intracranial aneurysms. Methods Our study prospectively included 26 consecutive patients with ruptured intracranial aneurysm managed at our institution in context of COVID-19 pandemic between March 1st, 2020 and April, 26th, 2020 (...
