Cluster-like Headache Secondary to Focal Cervical Myelitis.

Background: Cluster headache (CH) is characterized by attacks of severe periorbital pain associated with autonomic symptoms. As with other forms of primary headache, structural lesions should be excluded, particularly if the headache presents with an atypical pattern.

Case: We report a 41-year-old woman who had no previous history of primary headache and showed a poor response to medication for CH.
