Background: The incidence of central nervous system involvement has increased in the setting of acquired immune deficiency syndrome (AIDS). Although rarely reported, spinal cord compression, in the setting of AIDS, has been associated with primary lymphoma or opportunistic infections.
Case Report: The authors describe the case of a young man who was admitted to our institution with rapid and progressive paraplegia. Imaging studies revealed an extramedullary lesion compressing the spinal cord spanning 3 thoracic levels. Surgical treatment was performed, and the compressing process completely excised. Histologic examination of the lesion showed a chronic inflammatory tissue with many necrotic areas without signs of infection or lymphoma. The patient progressively regained normal strength in his legs and was discharged home.
Conclusions: In patients with HIV, chronic inflammation can lead to a lesion that compresses the spinal cord and should be considered in the differential diagnosis. Knowledge of this entity gains importance with the increasing incidence of HIV because timely excision can restore neurologic deficits. This condition may be considered a new clinical entity, the true incidence of which will be established using the diagnostic protocols provided and further case reports.

Chronic pain is a pervasive and debilitating condition with increasing implications for public health, affecting millions of individuals worldwide. Despite its high prevalence, the underlying neural mechanisms and pathophysiology remain only partly understood. Since its introduction 35 years ago, brain diffusion magnetic resonance imaging (MRI) has emerged as a powerful tool to investigate changes in white matter microstructure and connectivity associated with chronic pain.

This study presents the construction of a comprehensive spatiotemporal atlas of white matter tracts in the fetal brain for every gestational week between 23 and 36 wk using diffusion MRI (dMRI). Our research leverages data collected from fetal MRI scans, capturing the dynamic changes in the brain's architecture and microstructure during this critical period. The atlas includes 60 distinct white matter tracts, including commissural, projection, and association fibers.

Dysregulation of GABAergic inhibition is associated with pathological pain. Consequently, enhancement of GABAergic transmission represents a potential analgesic strategy. However, therapeutic potential of current GABA agonists and modulators is limited by unwanted side effects.
View Article and Find Full Text PDFObjective: While the association of a syrinx with a tethered spinal cord in the context of VACTERL (vertebral defects [V], imperforate anus or anal atresia [A], cardiac malformations [C], tracheoesophageal defects [T] with or without esophageal atresia [E], renal anomalies [R], and limb defects [L]) association is known, the incidence of idiopathic syrinxes among these patients has not previously been reported. The authors aimed to characterize the incidence of syrinxes and the pattern of congenital anomalies in pediatric patients with VACTERL association, with a specific focus on the presence of idiopathic syrinxes in this population.
Methods: An institutional database was retrospectively queried for all pediatric patients with VACTERL association.

Objective: The objective was to comprehensively investigate the clinical, molecular, and imaging characteristics and outcomes of H3 K27-altered diffuse midline glioma (DMG) in adults.
Methods: Retrospective chart and imaging reviews were performed in 111 adult patients with H3 K27-altered DMG from two tertiary institutions. Clinical, molecular, imaging, and survival characteristics were analyzed.
