How to Diagnose Arnold Chiari Malformation

A serious neurological condition, Chiari Malformation occurs when the cerebellum found in the bottom portion of the brain, falls through the base of the skull and squeezes down onto the spinal cord. The pressure causes symptoms such as headaches, balance problems and fullness in the ears.

Instructions

• 1

  Have a thorough medical exam, including history about your memory, balance, reflexes and motor skills. In some cases, Chiari is diagnosed when the doctor is screening for some other condition or problem.

• 2

  Undergo routine ultrasound exams, if pregnant. The ultrasound can help to identify spina bifida in your unborn baby, which can be caused by type II Chiari during pregnancy.

• 3

  Have a special MRI known as a cine MRI performed. This allows your doctor to measure the flow of spinal fluid and assess if it is being blocked by the cerebellum. It also relays images of organs and tissues in 3D and can help diagnose Chiari Malformation.

• 4

  Consider having further testing such as an x-ray of the head and neck to help identify any abnormalities of your bones and a CAT scan to assess for blood vessel abnormalities indicative of Chiari.

• 5

  Investigate other testing options which can help to diagnose Chiari Malformation. A sleep study test assesses a breathing pattern that may be indicative of Chiari malformation concerning the delivery of adequate oxygenation to the brain when sleeping.
