title: Two more secondary headaches mimicking chronic paroxysmal hemicrania. Is this the exception or the rule?
abstract: Two patients with headaches meeting the criteria of chronic paroxysmal hemicrania, as defined by the International Headache Society classification, are presented. Further investigations revealed a parasellar pituitary microadenoma in the first patient and a maxillary cyst in the second. Surgical removal of the lesions resulted in complete relief from headaches. The clinical features of this rare syndrome are discussed and suggest that a more detailed laboratory study and clinical follow-up is necessary in patients with chronic paroxysmal hemicrania.
