title: The Chiari-I malformation.
abstract: We have described the important clinical features and aspects of the Chiari-I malformations, with particular emphasis on Chiari-I malformation. Previously thought to be a rare finding with only minor significance, Chiari-I malformation is an important cause of a variety of symptoms, and will be diagnosed even more frequently as the use of MRI increases. The clinician must consider Chiari-I malformation in any patient with unexplained sensorineural hearing loss, headache, vertigo, ataxia, dysequilibrium, dysphagia or other cranial nerve symptom, especially if accompanied by more classic symptoms of this disorder, such as cervical pain or weakness.
