%0 Journal Article %T Abnormal Brain MRI in a Case of Acute Ataxia as the Only Sign of Abdominal Neuroblastoma %A M. Molla Mohammadi %A P. Karimzadeh %A A. Khatami %A F. Jadali %J Iranian Journal of Radiology %D 2010 %I Tehran University of Medical Sciences %X Ataxia is a movement disorder that may manifest an acute, intermittent, non progressive or"nchronic progressive course. Ataxia alone is rare as a paraneoplastic sign, especially if it is due to"nneuroblastoma (abdominal or chest)."nWe report an abdominal neuroblastoma in a two-year-old girl presenting with only acute ataxia"nand abnormal neuroimaging. Brain MRI showed abnormal signal finding in the medulla, pons,"ncorticospinal tract and the periventricular space. In the abdominal CT, a mass was detected"nin the right adrenal gland with calcification and the histopathologic examination re-vealed"nneuroblastoma."nWe suggest in children with acute ataxia, with or without opsoclonus-myoclonus, neuroblastoma"nshould be considered. %K Neuroblastoma %K Abnormal Neuroimaging Finding %K Acute Ataxia %U http://journals.tums.ac.ir/PdfMed.aspx?pdf_med=/upload_files/pdf/17564.pdf&manuscript_id=17564
