title: Paradoxical postural cerebrospinal fluid leak-induced headache: report of two cases.
abstract: We report two patients with a history of dural puncture who developed paradoxical postural cerebrospinal fluid leak-induced headache. The patients' headache worsened when they were in the recumbent position, and it improved when they were placed upright. Both patients had a history of migraine headache. The patients were successfully treated with autologous epidural blood patch. The mechanism for PPCLH is to be elucidated.
