A 73‐Year‐Old Man With Several Years of Difficulty Climbing Stairs and Frequent Tripping

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT A 73‐year‐old man presented with progressive weakness and atrophy predominantly affecting the distal finger flexors and quadriceps muscles. Electrophysiological studies demonstrated mixed myogenic and neurogenic features. Muscle MRI showed inflammatory changes, and muscle biopsy revealed granulomatous myositis with histologic features ...

Mendelian Randomization and Double Machine Learning Modeling Reveal Brain Imaging‐Derived Phenotypes as Functional Contributors to 18 Autoimmune Inflammatory Diseases

Advanced Science, EarlyView.
This schematic integrates the eight statistically significant causal relationships identified between 1,366 brain imaging‐derived phenotypes (IDPs) and 18 autoimmune inflammatory diseases (AIDs). Arrows indicate the direction of causality inferred from bidirectional two‐sample MR analyses.

Exploring the Vasculitis‐Tumors Link: Epidemiological Patterns, Mechanistic Insights, and Clinical Implications

Advanced Science, EarlyView.
This review outlines association between vasculitis and malignancies and provides practical value for clinicians in distinguishing primary vasculitis from malignancy‐associated forms and optimizing patient surveillance, improving recognition of tumor‐associated vasculitis to reduce the risk of misdiagnosis, supporting more accurate clinical decision ...

Reactive lymphoid hyperplasia of the liver: A case report featuring characteristic nodular and perinodular enhancement

Radiology Case Reports
A 53-year-old female with primary biliary cholangitis was referred for the evaluation of a hepatic nodule identified during routine imaging. Ultrasonography revealed a homogeneous, hypoechoic, 18 mm nodule in segment 3 of the liver. On dynamic CT and MRI,

Hippocampal T2 hyperintensities on 7 Tesla MRI

NeuroImage: Clinical, 2013
Hippocampal focal T2 hyperintensities (HT2Hs), also referred to as hippocampal sulcal cavities, are a common finding on Magnetic Resonance (MR) images. There is uncertainty about their etiology and clinical significance. In this study we aimed to describe these HT2Hs in more detail using high resolution 7 Tesla MR imaging, addressing 1) the MR signal ...

A Comparison of Substantia Nigra T1 Hyperintensity in Parkinson's Disease Dementia, Alzheimer's Disease and Age-Matched Controls: Volumetric Analysis of Neuromelanin Imaging [PDF]

, 2016
Objective: Neuromelanin loss of substantia nigra (SN) can be visualized as a T1 signal reduction on T1-weighted high-resolution imaging. We investigated whether volumetric analysis of T1 hyperintensity for SN could be used to differentiate between ...

Infantile‐Onset Ascending Hereditary Spastic Paraplegia due to a Homozygous ALS2 Exons 24–25 Deletion: Expanding the Genotypic Spectrum

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT We describe a novel homozygous intragenic deletion in the ALS2 gene in an 8‐year‐old boy with Infantile‐onset Ascending Hereditary Spastic Paraplegia (IAHSP) and oculomotor apraxia, thereby contributing to the expanding genetic landscape of ALS2‐related disorders.
