Clinical Applications of Electrical Conductivity Imaging Using MRI

Journal of Magnetic Resonance Imaging, Volume 63, Issue 5, Page 1224-1245, May 2026.
ABSTRACT Magnetic resonance imaging (MRI) has emerged as a noninvasive technique for probing the electrical properties of biological tissues: electrical conductivity and relative permittivity. This review focuses on the electrical conductivity and provides a comprehensive overview of applications across both low‐ and high‐frequency regimes.

Non‐Syndromic Tumefactive Demyelinating Lesions in the Pediatric Population: Four Case Reports and Review of the Literature

Annals of the Child Neurology Society, Volume 4, Issue 1, Page 87-94, March 2026.
ABSTRACT Introduction Tumefactive demyelinating lesions (TDLs) are large lesions (> 2 cm) seen in demyelinating syndromes such as multiple sclerosis, myelin oligodendrocyte glycoprotein antibody‐associated disorder, and neuromyelitis optica spectrum disorder. They rarely occur in children and most often have a monophasic course.

Quantitative Assessment of Upper Limb Ataxia Using a Virtual Reality‐Based Evaluation System

Annals of Clinical and Translational Neurology, Volume 13, Issue 1, Page 180-192, January 2026.
ABSTRACT Objective Cerebellar ataxia impairs coordination and balance, reducing quality of life. Conventional clinical scales, including the Scale for the Assessment and Rating of Ataxia (SARA) and the International Cooperative Ataxia Rating Scale (ICARS), are widely used to assess ataxia but are limited by subjectivity and inter‐rater variability ...

A Blind Spot in the Diagnostic Field: The Challenging Diagnosis of Tumefactive Multiple Sclerosis

Case Reports in Neurological Medicine, 2018
Tumefactive Multiple Sclerosis (TMS) is a rare variant with 1 per 1000 cases of MS and 3 per million cases per year. TMS can mimic clinical and radiological features of a neoplasm, infarction, or abscess and therefore can be diagnostically challenging ...

Advanced Imaging Applications in Tumefactive Demyelination – Literature Review With an Illustrative Case Report

Clinical Neuroimaging, Volume 3, Issue 1, 2026.
ABSTRACT Background and Purpose Solitary tumefactive demyelinating lesions (TDLs) represent an uncommon but clinically significant manifestation of central nervous system demyelination and pose a major diagnostic challenge due to their radiologic resemblance to high‐grade gliomas, primary central nervous system lymphoma, and other mass‐like lesions ...

Double Anti‐NMO and Anti‐MOG Positivity in a Patient With Metastatic Renal Carcinoma: First Reported Case

Case Reports in Neurological Medicine, Volume 2026, Issue 1, 2026.
Background Neuromyelitis optica spectrum disorder (NMOSD) and myelin oligodendrocyte glycoprotein‐associated disease (MOGAD) are central nervous system (CNS) demyelinating disorders characterized by autoantibodies targeting aquaporin‐4 (AQP4) and MOG, respectively.

Endonasal Endoscopic Approach for Bone Spicule Removal: A Case Report

Case Reports in Otolaryngology, Volume 2026, Issue 1, 2026.
During rhinoplasty surgery, tiny bone spicules (BSs) can form, particularly if blunt tools are used. If these BSs are not noticed and removed intraoperatively, they can cause cosmetic problems and nasal swelling postoperatively. A patient who underwent open rhinoplasty 2 years ago presented with a painless swelling causing cosmetic problems near the ...

Tumefactive Fat Necrosis with Multinucleate Giant Cell Reaction Mimicking Recurrent Renal Cell Carcinoma following Percutaneous Renal Cryoablation

Case Reports in Urology, 2019
Multinucleate Giant Cell (GC) reaction is a biological response that occurs secondary to infection, an implanted foreign body, tissue injury, or inflammation. In rare instances GC reactions have been reported following tissue ablation.
