Severe headaches in the lower back of the head are the most common childhood symptom of Chiari malformation, according to Ian Butler, M.D., vice-chairman of the neurology department at Memorial Hermann Hospital and director of the pediatric neurology division at The University of Texas Medical School at Houston. On Wed., March 16 at 5:30 p.m. CST, Butler's colleague, pediatric neurosurgeon Stephen A. Fletcher, D.O., treated a Chiari malformation during a live, global Webcast from Memorial Hermann Children's Hospital in Houston, Texas.
In Chiari malformations, parts of the cerebellum extend into the spinal canal, increasing pressure and inhibiting the flow of spinal fluid. Two small protrusions at the base of the cerebellum, called tonsils, are normally positioned inside the skull. In the Type I Chiari malformation, the most common and least severe form of the condition, the tonsils extend down into the spinal canal. In more severe forms, additional structures of the brain may migrate downward as well.Severe headaches in the lower back of the head are the most common childhood symptom of Chiari malformation, according to Ian Butler, M.D., ...all »Severe headaches in the lower back of the head are the most common childhood symptom of Chiari malformation, according to Ian Butler, M.D., vice-chairman of the neurology department at Memorial Hermann Hospital and director of the pediatric neurology division at The University of Texas Medical School at Houston.
