title: SUNA syndrome with seasonal pattern.
abstract: SUNA is a trigeminal autonomic cephalalgia (TAC) characterized by short unilateral attacks centered on the ophthalmic trigeminal distribution, and accompanied by at least one of a number of cranial autonomic symptoms that can include lacrimation, redness of the ipsilateral eye, nasal congestion, rhinorrhea, and eyelid edema. It exists in episodic and chronic form. We have described an atypical case of episodic SUNA with an exclusive seasonal pattern as previously reported in other trigeminal autonomic cephalalgia, commonly known as TACs.
