Neurofibromatosis type 1 (NF1) is monogenic neurodevelopmental disorder caused by mutation of NF1 gene, which leads to increased susceptibility to various tumors formations. Additionally, majority of patients with NF1 are experience high incidence of cognitive deficits. Particularly, we review the growing number of reports demonstrated a higher incidence of autism spectrum disorder (ASD) in individuals with NF1. In this review we also discuss face validity of preclinical Nf1 mouse models. Then we describe discoveries from these animal models that have uncovered the deficiencies in the regulation of Ras and other intracellular pathways as critical mechanisms underlying the Nf1 cognitive problems. We also summarize and interpret recent preclinical and clinical studies that point toward potential pharmacological therapies for NF1 patients.

December 2024
Department of Orthopedics and Trauma-Surgery P32, University Hospital Center IBN Rochd, Casablanca, Morocco.
Introduction: Neurofibromas are rare benign tumors of peripheral nerve sheaths, and hand involvement is particularly uncommon. This case report presents a large neurofibroma located in the thenar region, a critical area for thumb opposition and hand dexterity, posing unique surgical challenges.
Presentation Of Case: A 23-year-old female presented with a 3-year history of a progressively enlarging mass in the thenar region of the right hand, accompanied by nocturnal pain but no neurological deficits.

Background/aim: Neurofibromatosis type 1 (NF1) is a genetic disorder with an incidence of approximately one in 3,000. More than half of the patients have new de novo pathogenic variants of the NF1 gene. In most family cases, all family members share an identical NF1-variant.

Department of Diagnostic and Interventional Radiology and Nuclear Medicine, University Medical Center Hamburg-Eppendorf, Martinistraße 52, 20246, Hamburg, Germany.
Background: To intraindividually compare the diagnostic performance of positron emission computed tomography (F-18-FDG-PET/CT) and diffusion-weighted magnetic resonance imaging (DW-MRI) in a non-inferiority design for the discrimination of peripheral nerve sheath tumours as benign (BPNST), atypical (ANF), or malignant (MPNST) in patients with neurofibromatosis type 1 (NF1).
Results: In this prospective single-centre study, thirty-four NF1 patients (18 male; 30 ± 11 years) underwent F-18-FDG-PET/CT and multi-b-value DW-MRI (11 b-values 0 - 800 s/mm²) at 3T. Sixty-six lesions corresponding to 39 BPNST, 11 ANF, and 16 MPNST were evaluated.

The Leo M. Davidoff Department of Neurological Surgery, Albert Einstein College of Medicine, Montefiore Medical Center, Bronx, NY 10467, USA.
Background: Calvarial defects in NF1 are rare and lack standardized management guidelines. This study seeks to shed light on calvarial defects in NF1 patients with extensive skull erosion.
Methods: This case report focuses on clinical and radiological presentations and surgical interventions during six years of follow-up, comparing the results with those in the literature.
