A 46-year-old woman reported headache with migraine without
aura and SUNCT symptoms. A previous diagnosis of pituitary
macroadenoma was confirmed with MR and an increased prolactin.
Cabergoline was started with improvement of symptoms. An imaging
follow-up showed a reduction of the macroadenoma (Figure 1).
Pituitary adenoma is a intracranial tumor that has been reported
in about 8% of patients with SUNCT. Dural stretch and hormonal
dysfunction are possible mechanisms for this association. The fact
that tumor and SUNCT were ipsilateral and that headache improved
after cabergoline may suggest an association between these
entities, supporting MR investigation when this type of headache is
diagnosed.
