Chiari type I malformation (HP:0007099)help
Term ID: 7099
Name: Chiari type I malformation
Synonym: Arnold Chiari type I malformation; Arnold-Chiari type I malformation; Chiari I malformation
Definition: Arnold-Chiari type I malformation refers to a relatively mild degree of herniation of the posteroinferior region of the cerebellum (the cerebellar tonsils) into the cervical canal with little or no displacement of the fourth ventricle. It is characterized by one or both pointed (not rounded) cerebellar tonsils that project 5 mm below the foramen magnum, measured by a line drawn from the basion to the opisthion (McRae Line)
