MRV Head There is no relevant literature to support the use of MRV head in the initial evaluation of a child with recurrent ataxia. Variant 4: Child. Chronic progressive ataxia. Initial imaging. Chronic progressive ataxia is a frequent presentation of ataxia in children. Signs and symptoms are typically of >2 months duration, but occasionally only a few weeks of symptoms may be present [5,14,34]. Cerebellar tumors, brain stem gliomas, and inflammatory disorders are collectively a common cause of chronic progressive ataxia in childhood [1,4,5,25]. Less commonly, inherited ataxias cause chronic progressive ataxias in children [1,4,5,25]. Inherited ataxias are a heterogenous group of clinically and genetically distinguished neurodegenerative disorders, which include autosomal dominant cerebellar ataxias, such as spinocerebellar ataxias, and autosomal recessive cerebellar ataxias, such as Friedreich ataxia. Imaging plays an important role in children with chronic progressive ataxias. Brain imaging is crucial in the assessment of children with suspected brain tumors. In children with inherited chronic progressive ataxias, certain imaging findings can be helpful in the diagnostic workup [1,4,11,28,39-47]. Several hereditary cerebellar ataxias disorders have a progressive clinical course and varying progression of cerebellar hemispheric and vermian volume loss. In addition to cerebellar and vermian atrophy, associated signal abnormality and atrophy of the spinal cord and additional areas of the brain may be seen in certain conditions. Initial imaging provides a baseline for assessment of these abnormalities. Because of the phenotypic heterogeneity and the progressive nature of hereditary cerebellar ataxias, imaging in early childhood may be normal or subtly abnormal with imaging abnormalities becoming more apparent on follow up [14,46,48].
