Isolated Extramedullary Trigeminal Nerve Root Lesion in Neuromyelitis Optica Spectrum Disorders With Aquaporin-4 Immunoglobulin G.

Cerebral Attack With Cortical-Leptomeningeal Involvement and Seizures in AQP4-IgG-Positive Neuromyelitis Optica Spectrum Disorder.

Neuromyelitis optica spectrum disorder (NMOSD) rarely presents with corticalleptomeningeal involvement. A 47-year-old woman with aquaporin-4 immunoglobulin G (AQP4-IgG)-positive NMOSD developed acute headache, seizures, motor aphasia, and worsening right arm weakness. Brain magnetic resonance imaging revealed a tumefac...

Subclinical Facial Nerve Enlargement in a Case of Chronic Demyelinating Peripheral Neuropathy

This case suggests that marked cranial nerve hypertrophy may be clinically unapparent in some hereditary polyneuropathies and supports future correlation of temporal bone pathology with imaging and genotype in confirmed cases.

Bony trigeminal nerve entrapment in autosomal dominant osteopetrosis: a rare cause of secondary trigeminal neuralgia

Cranial bone disorders are a rare cause of secondary trigeminal neuralgia (TN), producing pain through progressive compression of the trigeminal nerve. We report a 46-year-old man with autosomal dominant osteopetrosis type 1 with left-sided refractory TN. Osteosclerosis of the petrous bone caused medial displacement...

Cerebellopontine Angle Meningioma Presenting as Trigeminal Neuralgia in a Patient with Meningiomatosis: A Case Report

Introduction: Trigeminal neuralgia (TN) is a paroxysmal neuropathic facial pain that is classified as classical, idiopathic or secondary. Space-occupying lesions account for approximately 4–6% of TN presentations, and meningioma is one of the most frequent culprits. The coexistence of TN with meningiomatosis—two or mor...

An Itch beyond the Skin: Syringomyelia Revealed by Localized Neuropathic Pruritus

Hemicerebral atrophy as an unusual central nervous system manifestation of Neurofibromatosis type 1: A case report

Neurofibromatosis type 1 is a widely known phakomatosis with highly variable manifestations. However, its presentation with hemicerebral atrophy resulting from an intracranial vasculopathy is uncommon, yet it poses a major health threat. We hereby report the case of a 6-year-old boy with the clinical features of Neurof...
