Background: Limited data exist on the significance of PET imaging and quantitative PET parameters in primary central nervous system (CNS) lymphoma due to its relative rarity. This study was conducted to investigate the prognostic value of a novel internal standardization indicator, the pontine-white matter (PW) score, in primary CNS lymphoma patients undergoing post-treatment F-FDG PET/CT and PET/MR imaging.
Methods: From January 2014 to December 2022, eligible patients with primary CNS lymphoma who underwent post-treatment PET imaging were enrolled. Using the FDG uptake of the pons and white matter as an internal reference, the PW score was graded based on the metabolism of the post-therapeutic lesion for each patient, and its associations with patients' prognosis were investigated.
Results: In total, 41 patients with post-treatment PET/CT and 49 patients with post-treatment PET/MR imaging were enrolled. ROC curve analysis indicated that the PW score possessed robust discriminative ability in distinguishing patients with worse outcomes. Furthermore, a higher PW score was significantly correlated with and identified as an independent prognostic indicator for, worse prognosis in both the PET/CT and PET/MR cohorts.
Conclusion: The study demonstrated that the PW score was an effective prognostic indicator for identifying post-treatment primary CNS lymphoma patients with worse outcomes.

CNS lymphoma is a rare form of non-Hodgkin lymphoma that primarily affects the brain, spinal cord, leptomeninges, or eyes, leading to severe neurological or ophthalmological complications. This case report details a 44-year-old male with human immunodeficiency virus and diffuse large B-cell lymphoma who experienced permanent vision loss due to optic perineuritis, a rare presenting symptom indicative of underlying CNS involvement. Despite previous remission, imaging revealed focal enhancements suggesting CNS lymphoma, highlighting diagnostic and management challenges in relapsed lymphoma, especially in immunocompromised patients.

Intramedullary spinal tuberculomas constitute a small percentage of spinal tuberculosis. These, in combination with brain tuberculomas, are an uncommon manifestation of central nervous system (CNS) tuberculosis. This report details a unique case of a 32-year-old retroviral disease-positive male who presented with a two-month history of symmetrical quadriparesis and recent seizures.

Primary central nervous system (CNS) lymphoma of the meninges is a rare tumor that originates in the meninges and does not show parenchymal or systemic spread. CNS involvement by natural killer (NK)/T-cell lymphoma accounts for only 2% of all extranodal NK/T-cell lymphomas, and primary NK/T-cell lymphoma of the meninges is even rarer. The present study reports a case of a 55-year-old male patient with primary NK/T-cell lymphoma.

Background/objectives: Anaplastic large cell lymphomas (ALCLs) present unique challenges due to their clinical and genetic heterogeneity. This study investigated the clinical characteristics of children diagnosed with systemic ALCL.
Methods: Retrospective data from 14 pediatric patients diagnosed with systemic ALCL at Valme University Hospital were studied.

There is an increasing awareness that B-cell lymphoma 2 (Bcl-2)-associated athanogene (BAG) proteins play critical roles in maintaining neural homeostasis, and that their dysregulation contributes to neurological disorders. This protein family of nine members is evolutionarily conserved, with each member having at least one BAG domain that binds to the nucleotide-binding domains of Heat Shock Protein (Hsp) 70 family members. Collectively, these proteins are essential for the proper functioning of the central nervous system (CNS).
