Abstract
|
|
|
Cluster headache is a form of trigeminal autonomic cephalalgias (TACs) characterized by unilateral headache accompanied by ipsilateral cranial autonomic features lasting for 15 to 180 minutes. Secondary cluster headache could be
associated with pituitary or peri-pituitary gland pathologies. A 22-year-old woman presented with a sudden -onset throbbing headache on the right periorbital and temporal area. She complained of headaches occurring 3 to 5 times per day accompanied by nausea, vomiting, photophobia, and phonophobia. Migraine medication were partially effective. Ten days after the first headache, she revisited with lacrimation, ptosis, periorbital edema and conjunctival hyperemia on the right side that were evident during the attack. Diagnostic work-ups revealed a pituitary microadenoma upon brain MRI and an elevated serum prolactin level. Her headache disappeared after administration of bromocriptine. Neuroimaging can be helpful in uncovering the pathologies of TAC. Bromocriptine can also be considered as a therapeutic option for TAC associated with prolactinoma.
