MRA Head MRA of the head in conjunction with MRA of the neck may be a helpful tool in assessing ataxia due to posterior circulation stroke, hemorrhage, or vascular malformation. However, a posterior circulation stroke is rare in children, and this investigation may need to be decided based on the clinical presentation and concern for acute cerebellar infarct [7]. Stroke or vascular malformations may present with ataxia in 1% to 3% of cases [20,26]. MRA Neck MRA of the neck in conjunction with MRA of the head may be a helpful tool in assessing ataxia due to posterior circulation stroke, hemorrhage, or vascular malformation. However, a posterior circulation stroke is rare in children, and this investigation may need to be decided based on the clinical presentation and concern for acute cerebellar infarct [7]. Stroke or vascular malformations may present with ataxia in 1% to 3% of cases [20,26]. Ataxia-Child MRV Head and Neck There is no relevant literature to support the use of MR venography (MRV) head and neck in the initial evaluation of a child with acute ataxia and no history of recent trauma. MRV Head There is no relevant literature to support the use of MRV head in the initial evaluation of a child with acute ataxia and no history of recent trauma. MIBG Scan In a child presenting with acute opsoclonus-myoclonus-ataxia syndrome, an MIBG scan may be helpful in the workup for identifying neuroblastoma, ganglioneuroblastoma, or ganglioneuroma as the causative etiology [2,13]. In the absence of any relevant literature, an MIBG scan may not be beneficial as a first-line imaging test in a child presenting with acute ataxia. CT Chest, Abdomen, and Pelvis In a child presenting with acute opsoclonus-myoclonus-ataxia syndrome with concern for neuroblastoma or ganglioneuroblastoma or ganglioneuroma, initial imaging with CT of the chest, abdomen, and pelvis with IV contrast may be helpful for diagnosis, although the clinical utility of CT as an initial imaging modality is less clear [2,13].
