2 MORE SECONDARY HEADACHES MIMICKING CHRONIC PAROXYSMAL HEMICRANIA - IS THIS THE EXCEPTION OR THE RULE

Two patients with headaches meeting the criteria of chronic paroxysmal hemicrania, as defined by the International Headache Society classifi cation, are presented. Further investigations revealed a parasellar pi tuitary microadenoma in the first patient and a maxillary cyst in the second. Surgical removal of the lesions resulted in complete relief fr om headaches. The clinical features of this rare syndrome are discusse d and suggest that a more detailed laboratory study and clinical follo w-up is necessary in patients with chronic paroxysmal hemicrania.
