Objective: Spontaneous nasal cerebrospinal fluid (CSF) leaks are frequently linked to idiopathic intracranial hypertension (IIH). The objectives of our study were: (1) to determine the rate of transverse venous sinus stenosis (TVSS) in patients with spontaneous nasal CSF leak and in patients with IIH without CSF (controls), and (2) to study the correlation between spontaneous nasal CSF leak and brain imaging features.
Study Design: A multicenter retrospective case-control study.
Article Synopsis
- The study aimed to assess the reliability of different methods for calculating cerebral blood volume (CBV) in glioblastomas using DSC-MRI, focusing on inter- and intra-observer variability.
- Twenty-seven untreated glioblastoma patients were analyzed by three observers using both the hotspot method and a volume method involving tumor segmentation, with specific parameters being recalculated two months later.
- Results showed that while the volume method provided good to excellent reproducibility for the maximum and normalized CBV values, the hotspot method demonstrated only fair reproducibility, highlighting that the volume method's parameter %rCBV > 2 could be beneficial for monitoring these tumors over time.
Background: Leptomeningeal enhancement (LME) is a key feature of Susac syndrome (SuS) but is only occasionally depicted on post-contrast T1-weighted images (T1-WI).
Objective: As post-contrast fluid-attenuated inversion recovery (FLAIR) may be more sensitive, our aim was to assess LME in SuS on this sequence.
Methods: From 2010 to 2020, 20 patients with definite SuS diagnosis were retrospectively enrolled in this multicentre study.
Standard Diffusion-Weighted Imaging in the Brain Can Detect Cervical Internal Carotid Artery Dissections.

Background And Purpose: The ICA is the most common site of cervical artery dissection. Prompt and reliable identification of the mural hematoma is warranted when a dissection is clinically suspected. The purpose of this study was to assess to capacity of a standard DWI sequence acquired routinely on the brain to detect dissecting hematoma related to cervical ICA dissections.

We compared the risk of future intracerebral hemorrhage (ICH), cSAH, and death in patients with CAA after cSAH and after lobar ICH. Methods- Consecutive patients with probable CAA, based on the Boston criteria, presenting with cSAH (CAA-cSAH) or lobar ICH (CAA-ICH) were included.
