Radiological Features of Scoliosis in Chiari I Malformation Without Syringomyelia.
STUDY DESIGN A retrospective radiographic analysis. OBJECTIVE The aim of this study was to investigate the scoliosis curve patterns/features and magnetic resonance imaging (MRI) tonsillar ectopia characteristics in Chiari I malformation without syringomyelia (CMI-only). SUMMARY OF BACKGROUND DATA The development of scoliosis associated with a CMI typically has been ascribed to the presence ...
متن کاملChildren with growth hormone deficiency and Chiari I malformation: a morphometric analysis of the posterior cranial fossa.
OBJECTIVE The posterior fossa (PF) has been found to be small in various forms of Chiari malformation. Explanations involving a connection between growth hormone deficiency (GHD) and Chiari I malformation (CIM) have been proposed. However, to date, no quantitative analysis of the PF of patients with CIM and GHD has been performed. Our study was performed to determine the geometry of the PF in c...
متن کاملPosterior fossa decompression with tonsillectomy in 104 cases of basilar impression, Chiari malformation and/or syringomyelia.
The prime objective in the surgical treatment of basilar impression (BI), Chiari malformation (CM) and/or syringomyelia (SM) is based on the restoration of the normal cerebrospinal fluid (CSF) dynamics at the craniovertebral junction through the creation of a large artificial cisterna magna. A small suboccipital craniectomy has been emphasized to avoid caudal migration of the hindbrain structur...
متن کاملAutomated posterior cranial fossa volumetry by MRI: applications to Chiari malformation type I.
BACKGROUND AND PURPOSE Quantification of PCF volume and the degree of PCF crowdedness were found beneficial for differential diagnosis of tonsillar herniation and prediction of surgical outcome in CMI. However, lack of automated methods limits the clinical use of PCF volumetry. An atlas-based method for automated PCF segmentation tailored for CMI is presented. The method performance is assessed...
متن کاملResolution of syringomyelia in ten cases of "up-and-down Chiari malformation" after posterior fossa decompression.
The authors describe ten cases of syringomyelia without hindbrain herniation depicted by preoperative magnetic resonance imaging (MRI) in supine position. However, the herniation was observed in all cases during the operation with the patient in sitting position. The postoperative MRI revealed an intense reduction of the syrinx in all patients, as well as it was also observed a clinical amelior...
