Differential Diagnosis of Cluster Headaches
Symptomatic cluster headaches - these headaches are rare and are thought to be caused by anatomical lesions (e.g., impacted molar teeth, arteriovenous malformations, and metastatic lung cancer). Markers that differentiate symptomatic cluster headache from true cluster headache include:
- presence of a low-grade headache that does not subside between headache attacks
- incomplete response to medication
- headaches do not occur at regular periodic cycles
- presence of neurologic signs other than the typical miosis and ptosis
