There are three headaches syndromes that are typically characterized by strictly unilateral and always same-sided attacks: cluster headache, "cervicogenic" headache, and chronic paroxysmal hemicrania (CPH). In rare cases, cluster headache also occurs bilaterally; "cervicogenic" headaches probably as well. We present a patient with a probable bilateral CPH. To our knowledge no such case has previously been described.
有三种头痛综合征，其典型特征为严格单侧且总是同一侧发作：丛集性头痛、“颈源性”头痛和慢性阵发性偏侧头痛（CPH）。在罕见情况下，丛集性头痛也会双侧发作；“颈源性”头痛可能也是如此。我们报告一例可能为双侧CPH的患者。据我们所知，此前尚无此类病例的描述。
