Charcot-Marie-Tooth neuropathy type 4B1 (CMT4B1) disease is a rare subtype of CMT4 with reported association of facial weakness, vocal cord paresis, chest deformities, and claw hands. We report the unusual occurrence of optic neuritis and cervical cord schwannoma in a male individual with confirmed CMT4B1 disease. Sequencing of the MTMR2 gene revealed a novel nonsense homozygous mutation c.1768C>T (p.Gln590*). The mutation was identified in affected relatives of the proband and a second, apparently unrelated, family. The rare association of optic neuritis or schwannoma with genetically confirmed CMT1A has been individually observed, but never with recessive CMT. To the best of our knowledge, the occurrence of optic neuritis and cervical cord schwannoma in the same patient has never been reported with any form of CMT including CMT4B1. In similar cases, we recommend immediate medical attention to rule out the possibility of schwannomas in patients with all demyelinating CMT subtypes in case of the development of focal neurological signs or acute worsening of clinical status.

Background: Growing evidence suggests a close association between circulating micronutrient levels and neuroimmune diseases. Nevertheless, the causal relationship between them remains unclear. Furthermore, due to confounding factors, many micronutrients implicated in these diseases remain unidentified.

We present the case of a 54-year-old patient treated with cemiplimab, an immune checkpoint inhibitor (ICI), for multiple basal cell carcinomas in the context of Gorlin Goltz syndrome. Gorlin Goltz syndrome is an autosomal dominant multisystem disorder characterized, among other features, by multiple early-onset basal cell carcinomas (BCCs). After receiving Cemiplimab, she developed aquaporin-4 antibody (AQP4-Ab) positive neuromyelitis optica spectrum disorder (NMOSD).

Background: Headache is a common but underrecognized symptom in optic neuritis (ON), with potential implications for diagnosis and management.
Objective: To assess the clinical and radiological factors associated with headache in patients with acute ON.
Methods: We conducted a retrospective case-control study in a tertiary hospital in Bogotá, Colombia (2022-2024).

A man in his 30s presented with sudden vision loss in the right eye and diminished vision in the left eye accompanied by headache. Clinical findings included bilateral disc oedema, reduced visual acuity in both eyes (right eye>left eye), dense premacular haemorrhage in the right eye and impaired colour vision. Blood tests were positive for serum myelin oligodendrocyte glycoprotein (MOG) antibodies, confirming MOG-associated optic neuritis (ON).

Myelin oligodendrocyte glycoprotein (MOG) antibody-associated disease (MOGAD) is a demyelinating disease of the central nervous system (CNS) that manifests as optic neuritis, transverse myelitis, acute disseminated encephalomyelitis, and cortical encephalitis. Some patients with MOGAD present with tumor-like brain lesions. However, hydrocephalus as an initial presentation is rare.
