Diffuse gliomas: insights into clinical and histopathological features and survival rates from two centers in a middle-income country.

Introduction: Gliomas are believed to arise from neuroglial stem cells and are histologically classified based on morphological similarities to normal neuroglial cells. This study aims to describe the clinical, histopathological, and demographic features of glioma patients treated in two reference centers in Colombia.

Methods: This descriptive cross-sectional study included all patients with a histologically confirmed glioma treated at two institutions in Bogotá, Colombia, between January 2015 and December 2023.

Differential tractography and whole brain connectometry in primary motor area gliomas resection: A feasibility study.

Objective: Establish the evolution of the connectome before and after resection of motor area glioma using a comparison of connectome maps and high-definition differential tractography (DifT).

Methods: DifT was done using normalized quantitative anisotropy (NQA) with DSI Studio. The quantitative analysis involved obtaining mean NQA and fractional anisotropy (FA) values for the disrupted pathways tracing the corticospinal tract (CST), and white fiber network changes over time.
