Purpose. To evaluate the correlation between MRI and histopathological findings in patients with mammographically detected 3-5 BI-RAD (Breast Imaging Reporting And Data Systems) microcalcifications and to allow a better surgical planning. Materials and Method. 62 female Patients (age 50 ± 12) with screening detected 3-5 BI-RAD microcalcifications underwent dynamic 3 T contrast-enhanced breast MRI. After 30-day (range 24-36 days) period, 55 Patients underwent biopsy using stereotactic vacuum-assisted biopsy (VAB), 5 Patients underwent stereotactic mammographically guided biopsy, and 2 Patients underwent MRI-guided VAB. Results. Microhistology examination demonstrated 36 malignant lesions and 26 benign lesions. The analysis of MRI findings identified 8 cases of MRI BI-RADS 5, 23 cases of MRI BI-RADS 4, 11 cases of MRI BI-RADS 3, 4 cases type A and 7 cases type B, and 20 cases of MRI BI-RADS 1-2. MRI sensitivity, specificity, positive predictive value, and negative predictive value were 88.8%, 76.9%, 84.2%, and 83.3%, respectively.

Can ChatGPT4-vision identify radiologic progression of multiple sclerosis on brain MRI?
Eur Radiol Exp
January 2025
St Vincent's University Hospital, Dublin, Ireland.
Background: The large language model ChatGPT can now accept image input with the GPT4-vision (GPT4V) version. We aimed to compare the performance of GPT4V to pretrained U-Net and vision transformer (ViT) models for the identification of the progression of multiple sclerosis (MS) on magnetic resonance imaging (MRI).
Methods: Paired coregistered MR images with and without progression were provided as input to ChatGPT4V in a zero-shot experiment to identify radiologic progression.

Epilepsy Unit - Sleep Disorders Unit, Fondazione IRCCS Istituto Neurologico Carlo Besta, Milan, Italy.
Background: Temporal lobe epilepsy with isolated amygdala enlargement (TLE-AE) still lacks a definite characterization and controversies exist.
Methods: We conducted a retrospective study identifying brain MRI scans with isolated AE between 2015 and 2021. We collected clinical and paraclinical data of patients with TLE-AE and evaluated the outcome.

Background And Objective: Neuronal intranuclear inclusion disease (NIID) is a multifaceted disorder impacting both the central and peripheral nervous systems. This study aims to investigate the clinical and electrophysiological characteristics of peripheral neuropathy in patients with NIID.
Methods: In this cross-sectional study, patients diagnosed with NIID were prospectively recruited from multiple centers across China between October 2017 and May 2024.
Cerebral vasculitis related to neurosarcoidosis: a case series and systematic literature review.
J Neurol
January 2025
Department of Neurology, Alfried Krupp Hospital, Essen, Germany.
Cerebral vasculitis is a rare but severe manifestation of neurosarcoidosis (NS) that has received little attention. The aim of the present study was to characterize clinical and diagnostic features as well as potential treatment strategies of cerebral vasculitis related to NS. We assessed 29 patients with cerebral vasculitis related to NS (15 female, mean age at time of diagnosis 45 years, SD = 11.

Department of Neuropediatrics and Muscular Disorders, Medical Center, Faculty of Medicine University of Freiburg, University of Freiburg, Freiburg im Breisgau, Germany.
Objective: Hypothalamic hamartomas (HHs) are associated with pharmacoresistant epilepsy. Stereotactic radiofrequency thermocoagulation (SRT) shows promise as a disconnecting intervention. Although magnetic resonance imaging (MRI) is typically used to determine the attachment and intervention side, it presents challenges in cases of bilaterally attached HH, where the epileptogenic side is unclear.
