Article Synopsis
- DLGGs are rare brain tumors that can progress even after treatment, complicating effective planning for surgery and other therapies due to their infiltration into white matter tracts.
- The study involved five patients and analyzed DTI signals alongside traditional imaging methods to identify changes associated with tumor progression over a year.
- Results indicated that prior to visible changes on standard imaging, abnormal DTI signals in the tumor's periphery could indicate early tumor infiltration, suggesting a potential tool for predicting tumor behavior and adjusting treatment plans.
Article Synopsis
- The study aimed to track the outcomes of patients with brain arteriovenous malformations (AVMs) who were managed conservatively, revealing key statistics on related morbidity and mortality over a 10-year period.
- Out of 1010 patients initially recruited, 434 were analyzed, with a majority having unruptured low-grade AVMs, demonstrating a 5% occurrence of serious outcomes and a higher risk in those with a history of rupture or older age.
- During the follow-up of approximately 3.2 years, 8% of patients experienced major intracranial hemorrhages, highlighting the ongoing risks associated with conservative management of AVMs.
Background: Saccular aneurysms of the proximal A1 segment (SAPA) are rare, but their treatment is challenging and scarcely described in the literature. We report the immediate and long term outcomes of their endovascular management.
Methods: We retrospectively analyzed all consecutive SAPA cases treated endovascularly at our center between 2003 and 2023.
Intracranial aneurysm detection: an object detection perspective.

Purpose: Intracranial aneurysm detection from 3D Time-Of-Flight Magnetic Resonance Angiography images is a problem of increasing clinical importance. Recently, a streak of methods have shown promising performance by using segmentation neural networks. However, these methods may be less relevant in a clinical settings where diagnostic decisions rely on detecting objects rather than their segmentation.
View Article and Find Full Text PDFStenting of the dural venous sinuses has emerged as a therapeutic option for intracranial hypertension and pulsatile tinnitus. However, venous endovascular navigation faces challenges due to lower-quality roadmaps compared to arterial navigation. This study explores the application of three-dimensional (3D) rotational venography in assessing the cerebral venous vasculature and its potential for venous navigation.
