Cerebellar vermian hypoplasia in dogs.
Six dogs with cerebellar dysplasia, in which the cerebellar vermis was hypoplastic, are described. Clinical signs in these dogs were noted around 2 weeks of age and included ataxia, dysmetria, and intention tremors. A variable portion of the caudal cerebellar vermis was absent in each dog; portions of the cerebellar hemispheres and flocculus also were absent in some of them. Neurons in certain ...
متن کاملThe fetal cerebellum. Pitfalls in diagnosis and management.
Prenatal diagnosis of congenital and acquired cerebellar disorders is possible by the use of ultrasound (US) and magnetic resonance imaging (MRI). Although numerous studies have been conducted in this field, diagnostic uncertainties are still common in daily clinical practice. This review outlines five possible pitfalls in the diagnosis of fetal cerebellar disorders: confusion between different...
متن کاملCerebellar vermian hypoplasia in a Cocker Spaniel
An eight-week-old female Cocker Spaniel was presented with ataxia, dysmetria and intention tremor. At 16 weeks, the clinical signs did not progress. Investigation including imaging studies of the skull and cerebrospinal fluid analysis were performed. The computed tomography revealed a cyst-like dilation at the level of the fourth ventricle associated with vermal defect in the cerebellum. After ...
متن کاملUltrafast fetal MRI and prenatal diagnosis.
Improvements in magnetic resonance imaging (MRI) technology continue to provide faster scan times and higher resolution increasing the applications for fetal imaging. MRI is an adjunct to good prenatal ultrasound scan (US). It provides significant additional information that improves diagnostic accuracy in evaluation of the fetal brain, spine, neck, chest, abdomen, and urinary tract. MRI provid...
متن کاملThe Usefulness of Fetal MRI for Prenatal Diagnosis
PURPOSE Fast MRI has provided detailed and reproducible fetal anatomy. This study was performed to evaluate the usefulness of fetal MRI for prenatal diagnosis. MATERIALS AND METHODS Fifty-six fetuses with congenital abnormalities on ultrasonography were evaluated by fetal MRI from 2001 to 2004 in Severance Hospital. Final diagnosis was made by postnatal pathology, postnatal MRI, and other mod...
