[Description and prognostic value of cerebellar MRI lesions in children with severe acute ataxia].
The aim of this work was to evaluate NMR cerebellar abnormalities in children with severe acute ataxia. Among 8 consecutively observed children, NMR performed in 6 during the acute phase was pathological in 4, demonstrating hyperintense signal in the T2-weighed sequences of dentate nuclei (2 cases, associated in 1 with hyperintense signal in the medium cerebellar peduncle) or of the cerebellar cortex associated with cerebellar swelling (2 cases). NMR performed in 7 cases after at least 1 month of evolution showed cerebellar atrophy in 4 cases. After 1 to 6 years of clinical follow-up, 4/8 children had clinical sequellae, including 3 of the 4 children with initially abnormal NMR. Conversely, the 2 patients with initially normal NMR had a good clinical recovery. NMR during the acute phase gives informations on prognosis in patients with severe acute ataxia.
