SUNCT SYNDROME ASSOCIATED WITH PITUITARY TUMOR

ABSTRACT- For twelve years, the subject of this report, a 38-year-old man, presented a clinical condition compatible with the SUNCT (short-lasting unilateral neuralgiform headache attacks with conjunctival injec-tion and tearing) syndrome. He presented a stabbing and intense daily pain located in the left pre-auric-ular and temporal regions. Each of these intense pain attacks lasted around one minute and presented a f requency of two to eight times per day. The pain was associated with ipsilateral lacrimation, conjunctival injection and rhinorrhea. MRI revealed a pituitary tumor with little suprasellar extent. The subject’s serial assays of prolactin, GH, TSH and ACTH were within normal levels. Following transsphenoidal hypophysec-t o m y, with complete removal of the tumor, the subject no more presented pain. The pathological diagno-sis was non-secreting adenoma. Fourteen months after the surgery, he remains symptom-free. KEY WORDS: SUNCT, pituitary tumor, surgery, ultra- shorting headaches.
