MRV Head There is no relevant literature to support the use of MRV head in the initial evaluation of a child with acute ataxia following recent trauma. Ataxia-Child intermittent ataxia [34]. Recurrent ataxia in a child may be a manifestation of basilar migraines, benign paroxysmal vertigo, genetic disorders such as autosomal dominant episodic ataxia, and metabolic disorders [1,22,25,27,34,35]. Benign paroxysmal vertigo is typically diagnosed by history, physical examination, and when vestibular testing and neuroimaging are normal. Basilar migraines are typically diagnosed based on clinical symptoms and with normal neuroimaging. Autosomal dominant episodic ataxias are a clinically heterogeneous group (at least 6 types described), with imaging findings such as vermian atrophy described in type 2 episodic ataxia. Inborn errors of metabolism, such as intermittent maple syrup urine disease, pyruvate dehydrogenase deficiency, and Hartnup disease can also present with intermittent ataxia during times of stress or illness [1,36,37]; imaging in these cases may be helpful in identifying and characterizing the underlying neurometabolic disease. Children with rotational occlusion of the vertebral artery, also known as bow hunter syndrome, may present with episodic neurologic symptoms including ataxia [38]; however, this condition is rare enough that it is not a diagnostic target for initial evaluation for a child presenting with recurrent ataxia and interval normal neurology examination. CT Head There is no relevant literature to support the use of head CT in the initial evaluation of a child with recurrent ataxia. CT Complete Spine There is no relevant literature to support the use of CT complete spine in the initial evaluation of a child with recurrent ataxia. CTA Head and Neck There is no relevant literature to support the use of CTA head and neck in the initial evaluation of a child with recurrent ataxia.
