MRI Chest, Abdomen, and Pelvis In a child presenting with acute opsoclonus-myoclonus-ataxia syndrome, with clinical suspicion for neuroblastoma, ganglioneuroblastoma, or ganglioneuroma, MRI of the chest, abdomen, and pelvis without and with IV contrast may be helpful to identify the underlying mass [2,13]; however, there is no literature to support the use of this modality as an initial procedure. Variant 2: Child. Acute ataxia, history of recent trauma. Initial imaging. Head trauma is a rare but important cause of ataxia in children, accounting for approximately 5% of acute childhood ataxias [18]. Ataxia after recent head and neck trauma may be due to intracranial hemorrhage, cerebral contusion, concussion, or traumatic vertebral dissection [18,30]. CTA Head and Neck CTA head and neck may be useful in the diagnostic workup of a child presenting with acute ataxia with a recent history of trauma, because of a vertebral artery dissection that may result in a cerebellar stroke and present with ataxia. Although most vertebral artery dissections are extracranial in location, CTA of the head and neck may be more beneficial than either CTA head or CTA neck alone to assess entire extent of vascular injury. CTA Head CTA head in conjunction with CTA of the neck may be useful in the diagnostic workup if there is suspicion of traumatic vascular injury such as vertebral artery dissection that may result in a cerebellar stroke and ataxia. Ataxia-Child Although most vertebral artery dissections are extracranial in location, CTA of the head and neck may be more beneficial than either CTA head or CTA neck alone to assess entire extent of vascular injury. CTA Neck CTA neck in conjunction with CTA of the head may be useful in the diagnostic workup if there is suspicion of cervical trauma resulting in cervical vascular injury such as vertebral artery dissection that may result in a cerebellar stroke and ataxia.
