Cavernous malformations of the brain are low-flow vascular lesions that have a propensity to hemorrhage. Extensive surgical approaches are often required for operative cure of deep-seated lesions. A 23-year-old female presented with a cavernous malformation of the left posterior insula with surrounding hematoma measuring up to 3 cm. A minimally invasive (mini-)pterional craniotomy with a transsylvian approach was selected. Endoscopic assistance was utilized to confirm complete resection of the lesion. The minipterional craniotomy is a minimally invasive approach that provides optimal exposure for sylvian fissure dissection and resection of many temporal and insular lesions.

Increases in mean lesional iron content by quantitative susceptibility mapping (QSM) by ≥6% and/or vascular permeability by dynamic contrast enhanced quantitative perfusion (DCEQP) by ≥40% on MRI have been associated with new symptomatic hemorrhage (SH) in cerebral cavernous malformations (CCMs). It is not known if plasma biomarkers can reflect these changes within the lesion proper. This cohort study enrolled 46 CCM patients with SH in the prior year.

To evaluate the incidence of mortality, hemorrhage, and neurological deficits in treating intracranial arteriovenous malformations (AVMs) in patients over 18 through a comparative analysis of surgical approaches and other therapeutic modalities. A systematic review was conducted using MEDLINE, Embase, CENTRAL, and LILACS databases in November 2023. Inclusion criteria included clinical trials, cohorts studies, case-controls studies, and case series comparing patients over 18 undergoing surgery or microsurgery versus other treatments (radiosurgery, isolated embolization, and conservative treatment).

Objective: To evaluate iron deposition patterns in patients with cerebral cavernous malformation-related epilepsy (CRE) using quantitative susceptibility mapping (QSM) for detailed analysis of iron distribution associated with a history of epilepsy and severity.
Methods: This study is part of the Quantitative Susceptibility Biomarker and Brain Structural Property for Cerebral Cavernous Malformation Related Epilepsy (CRESS) cohort, a prospective multicenter study. QSM was used to quantify iron deposition in patients with sporadic cerebral cavernous malformation (CCMs).

Endothelial-mesenchymal transition (EndMT) is defined as an important process of cellular differentiation by which endothelial cells (ECs) are prone to lose their characteristics and transform into mesenchymal cells. During EndMT, reduced expression of endothelial adhesion molecules disrupts intercellular adhesion, triggering cytoskeletal reorganization and mesenchymal transition. Numerous studies have proved that EndMT is a multifaceted biological event driven primarily by cytokines such as TGF-β, TNF-α, and IL-1β, alongside signaling pathways like WNT, Smad, MEK-ERK, and Notch.
