چکیده

The MR findings in a case of a Chiari type I malformation that resolved spontaneously over a 4-year period are presented. Differential growth of the skull and spine might have accounted for the resolution of this anomaly.

Conservative treatment of juvenile with Chiari I malformation, syringomyelia and scoliosis. Two case reports

Background Scoliosis improvement after surgical treatment of Chiari I and syrinx has been reported [1]. Incidence of scoliosis progression after decompression surgery has been reported as high as 48%. The conservative treatment with brace in these patients is not effective and scoliosis is typically progressive [2]. Spontaneous resolution of CT syrinx and Chiari I in paediatric population is un...

MR demonstration of ectopic fourth ventricular choroid plexus in Chiari II malformation.

An enhancing nodule was seen on T1-weighted enhanced scans at the tip of the caudally displaced cerebellar vermis in three patients with Chiari II malformation. The enhancing fibrovascular nodule found at the base of the cerebellum in patients with Chiari II malformation represents ectopic choroid plexus and should not be confused with a pathologic mass.

Characterization of CSF hydrodynamics in the presence and absence of tonsillar ectopia by means of computational flow analysis.

BACKGROUND AND PURPOSE Phase-contrast MR imaging (PCMR) has only partially characterized cyclic CSF flow and pressure, which, hypothetically, have a role in the pathogenesis of syrinx and symptoms in the Chiari I malformation. Our goal was to use computational flow analysis (CFA) to better understand CSF hydrodynamics. MATERIALS AND METHODS High-resolution MR images were obtained in a healthy...

MR imaging of Chiari II malformation.

High-field-strength MR imaging was performed in one patient with Chiari III and 19 patients with Chiari II malformations. The MR features were compared with descriptions in the literature and correlated with previously described surgical and postmortem findings and with the results of previous radiologic investigations in this group of patients. Several new observations were apparent from the M...

Phase-contrast MR imaging of the cervical CSF and spinal cord: volumetric motion analysis in patients with Chiari I malformation.

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...
