[Cluster-tic syndrome: two case reports]

Two patients with cluster-tic syndrome are reported. The first, a 43-years-old man, complaining of trigeminal pain in the right side of the face, accompanied by homolateral autonomic signs, such as ocular injection, sweating and drooped eyelid. The cluster attack was triggered by chewing, shaving and washing the face. The periodicity of bouts was six months. The pain was relieved by carbamazepine (800 mg/day). The second patient, a 43-year-old man, with an excruciant, neuralgic pain in the left side of the face, accompanied by tearing, conjuntival injection, drooped eyelid, rhinorrhea, photophobia and phonophobia. The neurologic examination showed triggered points in the first and second division of the trigeminal nerve. The patient was treated with verapamil (160 mg/day) and prednisone (60 mg/day), with relief of his symptoms. The periodicity of bouts was once a year. The literature was reviewed and 37 cases previosly reported are considered. We conclude that there are two different groups of patients. In the first group, the patients had cluster and trigeminal bouts in different time. In the second group, with only nine cases, the patients presented both cluster and trigeminal type of pain at the same time, as in the two cases reported here.
