Objective: To explove the clinical features of rare trigeminal autonomic cephalalgias (TAC),including short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) and paroxysmal hemicrania (PH). Methods: 2 SUNCT patients and 3 PH patients admitted between January 2007 and December 2010 were retrospectively reviewed. Clinical features and treatment were analyzed. Results: SUNCT and PH share the clinical features of severe ocular and temporal pain and prominent cranial parasympathetic autonomic features. The duration of headache ranges from 20 seconds to 30 minutes. Pain attacks from 8 to 100 per day. Indomethacin is specific treatment for PH and lamotrigine is useful to SUNCT. Conclusions: Clinical presentations and good response to some types of drugs are helpful in identifying the early diagnosis of SUNCT and PH.%目的:探讨伴有结膜充血及流泪的单侧短暂持续性神经痛样头痛(SUNCT)和阵发性偏侧头痛(PH)的临床特点.方法:回顾性分析2例SUNCT患者和3例PH患者的临床表现及治疗方法.结果:5例患者均表现为单侧眼眶、颞部的剧烈疼痛,并伴有同侧的颅内副交感神经激活症状,持续时间从20秒到30分钟,每天发作频率从8次到100次;SUNCT患者给予拉莫三嗪口服,阵发性偏侧头痛患者给予吲哚美辛口服,效果较好.结论:熟悉SUNCT和PH的临床特点,有利于早期诊断和治疗.
