Utility of MR Neurography for the Evaluation of Peripheral Trigeminal Neuropathies in the Postoperative Period [HEAD AND NECK IMAGING]
SUMMARY:
Peripheral trigeminal neuropathies are assessed by MR neurography for presurgical mapping. In this clinical report, we aimed to understand the utility of MR neurography following nerve-repair procedures. We hypothesized that postoperative MR neurography assists in determining nerve integrity, and worsening MR neurography findings will corroborate poor patient outcomes. Ten patients with peripheral trigeminal neuropathy were retrospectively identified after nerve-repair procedures, with postsurgical MR neurography performed from July 2015 to September 2023. Postsurgical MR neurography findings were graded as per po...

Sinonasal (Schneiderian) Tumors in the Temporal Bone: Case Series and Systematic Review [HEAD AND NECK IMAGING]
CONCLUSIONS:
The observed tumor patterns support the hypothesis that the Eustachian tube facilitates the spread of sinonasal epithelium–derived neoplasms from the sinonasal cavity to the temporal bone. Transtubal spread of sinonasal epithelium–derived neoplasms should be considered among the rare causes of middle ear masses. (Source: American Journal of Neuroradiology)

Does CISS MRI Reliably Depict the Endolymphatic Duct in Children with and without Vestibular Aqueduct Enlargement? [HEAD AND NECK IMAGING]
CONCLUSIONS:
CISS MR imaging substantially underdiagnoses EVA; however, when a type 3 endolymphatic duct is evident, there is a >99% likelihood of an EVA. (Source: American Journal of Neuroradiology)

Neurofilament Light Chain Levels Interact with Neurodegenerative Patterns and Motor Neuron Dysfunction in Amyotrophic Lateral Sclerosis [NEURODEGENERATIVE DISORDER IMAGING]
CONCLUSIONS:
Serum neurofilament light chains may be an important mediator between clinical symptoms and neuronal loss according to cortical thickness. Furthermore, MR imaging anomalies might have underestimated prognostic value because they seem to indicate higher serum neurofilament light chain levels. (Source: American Journal of Neuroradiology)

Prognostic Significance of Central Skull Base Remodeling in Chiari II Malformation [PEDIATRIC NEUROIMAGING]
CONCLUSIONS:
Pediatric patients with Chiari II malformation who ultimately required surgical hydrocephalus treatment had greater outward convexity of the basiocciput but had greater posterior atlanto-occipital membrane outward convexity only if the repair was performed postnatally. Together these measurements may be useful in predicting the need for hydrocephalus treatment. (Source: American Journal of Neuroradiology)

Expanding the Imaging Spectrum of Polymorphous Low-Grade Neuroepithelial Tumor of the Young in Children [PEDIATRIC NEUROIMAGING]
We present the imaging spectrum of neuroimaging features in a series of pediatric patients with a histologically and molecularly proved PLNTY diagnosis. Coarse calcifications are uncommon in children compared with the adult literature, and they may develop with time. The transmantle-like sign can be observed, and adjacent cortical dysplasia may be seen. Seizure recurrence may occur despite gross total resection of the tumor.

Comparison of Volumetric and 2D Measurements and Longitudinal Trajectories in the Response Assessment of BRAF V600E-Mutant Pediatric Gliomas in the Pacific Pediatric Neuro-Oncology Consortium Clinical Trial [PEDIATRIC NEUROIMAGING]
CONCLUSIONS:
Although there was no overall difference between volumetrics and 2D in classifying partial response assessment using BT-RADS, further prospective studies will be critical to elucidate how the observed differences in tumor 2D and volumetric trajectories affect clinical decision-making and outcomes in some individuals.

High-Grade Astrocytoma with Piloid Features: A Dual Institutional Review of Imaging Findings of a Novel Entity [BRAIN TUMOR IMAGING]
We present an image-centric review of HGAP and explore the association between HGAP and neurofibromatosis type 1. Data were collected from 8 HGAP patients treated at two tertiary care institutions between January 2020 and October 2023. Demographic details, clinical records, management, and tumor molecular profiles were analyzed. Tumor characteristics, including location and imaging features on MR imaging, were reviewed. Clinical or imaging features suggestive of neurofibromatosis 1 or the presence of NF1 gene alteration were documented. The mean age at presentation was 45.5 years (male/female = 5:3). Tumors were midline, l...

Arterial Spin-Labeling and DSC Perfusion Metrics Improve Agreement in Neuroradiologists Clinical Interpretations of Posttreatment High-Grade Glioma Surveillance MR Imaging--An Institutional Experience [BRAIN TUMOR IMAGING]
CONCLUSIONS:
Adding perfusion to contrast-enhanced MR imaging improved interrater agreement, rater agreement with consensus, and rater confidence in the interpretation of posttreatment high-grade glioma MR imaging, with the highest agreement and confidence scores seen with DSC-fractional tumor burden. Perfusion MR imaging also resulted in interpretation changes that could change therapeutic management in up to 20% of patients. (Source: American Journal of Neuroradiology)

Identifying Patients with CSF-Venous Fistula Using Brain MRI: A Deep Learning Approach [ARTIFICIAL INTELLIGENCE]
CONCLUSIONS:
This study developed a deep learning model that can predict the presence of a spinal CSF-venous fistula based on brain MR imaging in patients with suspected spontaneous intracranial hypotension. However, further model refinement and external validation are necessary before clinical adoption. This research highlights the substantial potential of deep learning in diagnosing CSF-venous fistulas by using brain MR imaging. (Source: American Journal of Neuroradiology)

Automated Detection of Cervical Spinal Stenosis and Cord Compression via Vision Transformer and Rules-Based Classification [SPINE IMAGING AND SPINE IMAGE-GUIDED INTERVENTIONS]
CONCLUSIONS:
This classification approach using a ViT model and rules-based classification accurately detects the presence of cervical spinal cord compression at the patient level. In this study, the ViT model outperformed both conventional CNN approaches at the section and patient levels. If implemented into the clinical setting, such a tool may streamline neuroradiology workflow, improving efficiency and consistency. (Source: American Journal of Neuroradiology)

Evaluation of Conditions for the Development of Cryogenic Spinal Cord Injury Using a Canine Model: An Experimental Study on the Safety of Cryoablation for Metastatic Spinal Tumors [NEUROINTERVENTION]
CONCLUSIONS:
This study showed that 10-minute spinal cryoablation with LETs (°C) of –37, –30, –27, –8, 0, and 1 caused cryogenic spinal cord injury. There was no evidence of cryogenic spinal cord injury in canines with LET of ≥4°C. The epidural temperature threshold for cryogenic spinal cord injury is between 1 and 4°C, suggesting that the epidural temperature should be maintained above at least 4°C to prevent cryogenic spinal cord injury.
