Article Abstract
Background: Risk factors for malignant tumours of the central nervous system (CNS) are largely unknown.
Methods: We pooled six European cohorts (N = 302,493) and assessed the association between residential exposure to nitrogen dioxide (NO), fine particles (PM), black carbon (BC), ozone (O) and eight elemental components of PM (copper, iron, potassium, nickel, sulfur, silicon, vanadium, and zinc) and malignant intracranial CNS tumours defined according to the International Classification of Diseases ICD-9/ICD-10 codes 192.1/C70.0, 191.0-191.9/C71.0-C71.9, 192.0/C72.2-C72.5. We applied Cox proportional hazards models adjusting for potential confounders at the individual and area-level.
Results: During 5,497,514 person-years of follow-up (average 18.2 years), we observed 623 malignant CNS tumours. The results of the fully adjusted linear analyses showed a hazard ratio (95% confidence interval) of 1.07 (0.95, 1.21) per 10 μg/m³ NO, 1.17 (0.96, 1.41) per 5 μg/m³ PM, 1.10 (0.97, 1.25) per 0.5 10m BC, and 0.99 (0.84, 1.17) per 10 μg/m³ O.
Conclusions: We observed indications of an association between exposure to NO, PM, and BC and tumours of the CNS. The PM elements were not consistently associated with CNS tumour incidence.

Parapharyngeal Space Ganglioneuroma in a Child: A Report of a Rare Case.
Cureus
August 2025
Pathology, Hanoi Medical University, Hanoi, VNM.
Parapharyngeal space (PPS) tumors are extremely rare in the pediatric population, accounting for a small fraction of all head and neck neoplasms. The majority of neoplasms in the PPS are benign tumors. We present a case of an eight-year-old male with a large PPS ganglioneuroma, who presented with a neck mass that had been progressing over five years with no symptoms of dysphasia.

Choroidal metastasis from occult cutaneous melanoma is rare and can masquerade as ocular inflammation. A 70‑year‑old man with sectoral anterior scleritis was found on multimodal imaging to have a solitary choroidal mass with mild periscleral fluid, prompting systemic evaluation that uncovered colonic polyps that, on histopathology, contained metastatic melanoma, a scalp primary, and widespread visceral, nodal, and intracranial metastases. Tumour cells stained HMB‑45, Melan‑A, and SOX10 positive, AE1/AE3 negative, and carried an NRAS‑Q61 mutation with wild‑type BRAF, confirming cutaneous origin.

We present a case of a 68-year-old male with advanced non-small cell lung cancer (NSCLC), PD-L1 negative and driver gene negative, who exhibited a significant abscopal effect following radiotherapy combined with systemic immunotherapy (sintilizumab) and chemotherapy. The patient achieved complete remission (CR) of intracranial metastases without cranial irradiation, suggesting a systemic immune response triggered by the combination of radiotherapy and immunotherapy. This case highlights the potential of radiotherapy combined with immuno-chemotherapy to induce abscopal effects, even in PD-L1 negative patients, and underscores the importance of further investigation into this therapeutic strategy.

Background: The coexistence of neuropsychiatric systemic lupus erythematosus (NPSLE) and primary diffuse large B-cell lymphoma (DLBCL) of the central nervous system (CNS) (PCNS DLBCL) is extremely rare in clinical practice. This article retrospectively analyzes the clinical manifestations, imaging examinations, pathological diagnosis, and treatment process of a patient with NPSLE, from the appearance of intracranial abnormal signal shadows to the final diagnosis of PCNS DLBCL.
Case Summary: A 32-year-old Chinese female patient had previously visited our hospital due to vomiting and delirium and was diagnosed with NPSLE.
