[Migraine? Arnold Chiari Malformation? Or Just a Migraine?].

Migraine? Arnold Chiari Malformation? Or Just a Migraine? In a young woman with a long-time headache in the sense of a migraine, a neurological reassessment including new findings of the existing MRI images of the skull resulted in the diagnosis of a Chiari malformation type 1. After successful operation of the MRI findings, the headache decreased significantly. However, since minor headaches of a different quality persist, a migraine plus malformation as an incidental finding are most likely.
