To determine the value of ultrasound scanning of the craniocervical junction in neonates via a posterior approach, we examined 50 infants with normal posterior fossae, 10 with congenital abnormalities, and eight with intracranial hemorrhage. Good evaluation of the cisterna magna, medulla, tonsils, vermis, cervical cord, and central canal was possible in most cases. In nine patients with spinal ...

Résumé La malformation d'Arnold Chiari de type 1 est définie par une hernie des tonsilles cérébelleuses dans le foramen magnum de plus de 5 mm. Les symptômes sont dominés par les céphalées surtout occipitales, les torticolis, et parfois des troubles de déglutition. Sur le plan ophtalmologique les anomalies de convergences, les paralysies oculomotrices et la diplopie sont les principaux signes c...

CASE REPORT The case involves a 22-year-old woman who presented with headache and decreased vision. She showed asymmetric papilledema, and a 6-mm tonsillar descent was observed in the image tests. She was diagnosed with secondary intracranial hypertension coinciding with the symptoms of a Chiari malformation (MC). DISCUSSION Chiari malformation type I is the most common in this group of malfo...

BACKGROUND Cervical spinal canal tapering may increase CSF velocities and pressures. One report suggests that the cervical spinal canal tapers more steeply in patients with Chiari I than in healthy subjects. The goal of this study was to test the conclusion by measuring spinal canal tapering in another cohort of patients. MATERIALS AND METHODS Consecutive patients with scoliosis and MR imagin...

BACKGROUND AND PURPOSE Most previous MR studies of the dynamics of Chiari I malformation have been confined to sagittal images and operator-dependent measurement points in the midline. To obtain a deeper insight into the pathophysiology of the Chiari I malformation, we performed a prospective study using axial slices at the level of C2 to analyze volumetric motion data of the spinal cord and CS...

OBJECTIVE To evaluate the frequency and degree of severity of abnormalities in the auditory pathways in patients with Chiari malformations type I and II. METHOD This is a series-of-case descriptive study in which the possible presence of auditory pathways abnormalities in 75 patients (48 children and 27 adults) with Chiari malformation types I and II were analyzed by means of auditory evoked ...

A neurogenic bladder is seldom described as the first manifestation of syringomyelia. A patient is reported with an extensive syrinx along the entire spinal cord and a Chiari type I malformation, who experienced dysaesthesia and weakness during shooting practice and presented with urinary retention.
