Introducción: Las malformaciones de Arnold-Chiari, son un grupo heterogéneo de desórdenes neurológicos caracterizados por alteraciones dentro de las regiones del cerebelo, tallo cerebral y unión cráneo-cervical; todas resultan en un desplazamiento inferior del cerebelo hacia el canal espinal por el...
This study characterized the clinical, radiological, ultrasound, and necroscopic findings of a case of Arnold-Chiari type II malformation in a Gir breed calf from Brazil. The animal was hospitalized at sixty days of age, in permanent sternal recumbency, cutaneous appendix at the 4th lumbar vertebra and k...
Much controversy remains on the current management of Chiari I deformity (CID) in
children, with many clinical, surgical and ethic-legal implications. The Brazilian Society
of Pediatric Neurosurgery (SBNPed, in the Portuguese acronym) has put together a
panel of experts to analyze updated published data ...
Hemifacial spasm (HS) is a movement disorder characterized by paroxysmal and
irregular contractions of the muscles innervated by the facial nerve. Chiari malformation
type I (CM I) is a congenital disease characterized by caudal migration of the
cerebellar tonsils, and surgical decompression of foramen m...
SUMMARY BACKGROUND Symptomatic Chiari Type I Malformation (CM) is treated with posterior fossa decompression with or without duroplasty. We have noticed some cases with concomitant severe cerebellar ataxia due to cerebellar atrophy. The aim of this study is to review the literature of CM associated wit...
Basilar invagination (BI) and Chiari malformation type I (CM-I) are very important anomalies that introduce instability and compression in the occipitocervical transition region and have complex clinical characteristics. These anomalies vary according to the affected structures. The present study revises...

Dyke-Davidoff-Masson Syndrome is a syndrome associated with refractory epilepsy. The Chiari II malformation is a complex congenital malformation of the brain. The authors report a case of a 15 years-old
adolescent presenting Dyke-Davidoff-Masson syndrome and Chiari type II malformation association. This ...
RESUMEN Se revisó la literatura existente sobre la Malformación de Chiari Tipo I en el adulto, haciendo énfasis en su diagnóstico imagenológico y tratamiento médico-quirúrgico. La malformación de Chiari es una enfermedad poco frecuente. Representa entre el 1 y el 4 % de todas las patologías neur...

ABSTRACT We proposed a 3D model to evaluate the role of platybasia and clivus length in the development of Chiari I (CI). Using a computer aided design software, two DICOM files of a normal CT scan and MR were used to simulate different clivus lengths (CL) and also different basal angles (BA). The final ...
