Portable Ultra‐Low‐Field MRI in Outpatient Neurology: An Examination of Clinical Performance and Patient Experience

Journal of Neuroimaging, Volume 36, Issue 4, July/August 2026.
ABSTRACT Background and Purpose Brain magnetic resonance imaging (MRI) is an essential component for outpatient neurological evaluation, though access to timely imaging at the point of care is not feasible for most outpatient neurology practices. Portable ultra‐low‐field MRI systems offer a potential solution, but studies describing their clinical ...

Optic Nerve Sheath Meningioma in the First Decade of Life: Case Report and Review of the Literature

Case Reports in Ophthalmology, 2012
Background/Aim: Tumors of the optic nerve are mostly either optic nerve gliomas or optic nerve sheath meningiomas (ONSMs). While gliomas occur in children, most meningiomas are slow-growing tumors affecting middle-aged individuals with progressive visual

Deciphering and Targeting the Schwannoma‐Neuron‐Macrophage Crosstalk for the Treatment of Schwannomatosis and Associated Pain

Advanced Science, Volume 13, Issue 26, 8 May 2026.
We established patient‐derived SWN cell lines and orthotopic PDX models that recapitulate patient pain phenotypes, alongside a novel intravital DRG imaging platform to track macrophage infiltration and neuronal pain responses. Using these models, we define HMGB1–CCL2–IL‐6 signaling crosstalk driving pain and identify EGF signaling as a key regulator of

Pathogenic Neurofibromatosis type 1 gene variants in tumors of non‐NF1 patients and role of R1276

FEBS Open Bio, Volume 16, Issue 4, Page 803-813, April 2026.
Somatic variants of the neurofibromatosis type 1 (NF1) gene occur across neoplasms without clinical manifestation of the disease NF1. We identified emerging somatic pathogenic NF1 variants and hotspots, for example, at the arginine finger 1276. Those missense variants provide fundamental information about neurofibromin's role in cancer.

Novel NOTCH3 alteration expanding the molecular spectrum of pericytic tumours: report of two cases

Histopathology, Volume 88, Issue 4, Page 922-927, March 2026.
Introduction Myofibromas are part of the pericytic tumour family, which includes myopericytomas, glomus tumours and angioleiomyomas. While they typically display benign behaviour when arising in the skin and subcutaneous tissues of the head and neck, rare aggressive variants have been reported, particularly those with visceral or intracranial ...
