BACKGROUND: A 63-year-old woman with chronic atrial fibrillation treated with warfarin was admitted to emergency for coma and complete vertical gaze palsy. Investigations: Brain CT and MRI, echo-colour Doppler sonography of the supraaortic vessels, angio-CT of the intracranial vessels, EEG, transesophageal echocardiogram, biohumoral tests. Brain CT and MRI scans showed bilateral thalamic lesions with involvement of the right midbrain; EEG showed a diffuse alpha rhythm prevalent on the posterior regions; echo-colour Doppler sonography of the supraaortic vessels showed marked reduction of blood flow in the right vertebral artery; angio-CT scans showed occlusion of the right vertebral artery and a significant filling defect of the first part of the right posterior cerebral artery (P1) from which the artery of Percheron arises. A follow-up angio-CT showed a complete recanalization of P1. Diagnosis: Percheron artery syndrome. Treatment and Management: Aspirin, neurorehabilitation.

: Canine tooth syndrome is a rare condition defined by the simultaneous presence of superior oblique palsy and Brown syndrome, resulting from pathological changes in the trochlear region. This syndrome can develop through various mechanisms, including dog bites, head trauma, infections, inflammation, and scarring. This report highlights its occurrence following sinus surgery for the first time.

Background: While automated methods for differential diagnosis of parkinsonian syndromes based on MRI imaging have been introduced, their implementation in clinical practice still underlies considerable challenges.
Objective: To assess whether the performance of classifiers based on imaging derived biomarkers is improved with the addition of basic clinical information and to provide a practical solution to address the insecurity of classification results due to the uncertain clinical diagnosis they are based on.
Methods: Retro- and prospectively collected data from multimodal MRI and standardized clinical datasets of 229 patients with PD (n = 167), PSP (n = 44), or MSA (n = 18) underwent multinomial classification in a benchmark study comparing the performance of nine machine learning methods.

Background: Laminectomy and fusion (LF) and laminoplasty (LP) are common treatments for cervical spondylotic myelopathy and myeloradiculopathy. While both procedures show similar clinical improvement, LF requires bony fusion while LP offers motion preservation. Cervical sagittal alignment and horizontal gaze maintenance are key outcome measures, but their comparative effects between LF and LP remain unclear.

Objectives: Niemann-Pick type C (NPC) is a rare, autosomal recessive, neurodegenerative disorder caused by biallelic pathogenic variants in the or genes, leading to lysosomal lipid accumulation. NPC has an incidence of 1 in 100,000 live births and presents with a wide range of symptoms affecting visceral organs and the central nervous system. We aim to describe the diverse clinical presentations of NPC through case studies.
