title: [Two cases of spontaneous intracranial hypotension with bilateral chronic subdural hematomas].
abstract: Spontaneous intracranial hypotension (SIH) is characterized by postural headaches without obvious cause and is occasionally related to chronic subdural hematomas (CSHs). Brain sag due to decrease in cerebrospinal fluid, and growing CSHs may occur secondary to a decrease in intracranial pressure. Therapy for this condition differs from that for mere traumatic CSHs and is controversial. We report 2 cases of CSH related to SIH. One patient required drainage of the CSHs and an epidural self-blood patch. Furthermore, this patient had to undergo reoperation for drainage of the CSHs. The other patient was cured after the first time the CSHs were drained.
