Diagnosis and surgical therapy of spontaneous intracranial hypotension.

Abstract

Spontaneous intracranial hypotension (SIH) is a serious medical condition caused by loss of cerebrospinal fluid at the level of the spine, which, when not treated, may cause substantial long-term disability and increase morbidity. The following video summarizes the necessary steps for successful diagnosis and treatment of SIH, starting with a brain and spine magnetic resonance imaging, followed by dynamic myelography. Because an epidural bloodpatch did not provide a lasting relief, the patient underwent surgery which demonstrated a ventral dural slit caused by an osteodiscogenic microspur. In the 1-month follow up, the patient was symptom free. This video is meant to raise awareness of SIH among clinicians in order to increase general sensitivity for this diagnosis.
