Arnold Chiari, also known as Chiari Malformation (CM), is the name given to a group of deformities of the hindbrain (Cerebellum, Pons, And Medulla Oblongata) that range from herniation of the posterior fossa contents outside of the cranial cavity to absence of the cerebellum with or without other associated intracranial or extra cranial defects such as hydrocephalus, syrinx or spinal. In this malformation group CM in all of its forms may produce neuronal dysfunctions of the brainstem, cerebellum, cranial nerves, medulla, and upper spinal cord. Evoked Potentials (EPs) can be useful for informing the clinician and the patient about the existence of objective neurophysiological abnormalities. In this review, we aim to review CM neuro-radiologically at the diagnosis stage and to emphasize the importance of neurophysiological recognition of CM in the early stage, especially in asymptomatic patients.
