title: [Headache can be caused by spontaneous intracranial hypotension].
abstract: Spontaneous intracranial hypotension (SIH) is an uncommon condition associated with postural headache, nausea and dizziness. It is believed to be secondary to a dural tear with resultant cerebrospinal fluid (CSF) leak. This is a case report of a pregnant woman (gestational age 31 weeks) who contacted an obstetric department because of severe headache. Pre-eclamp-sia was suspected, but not found. An MRI showed a CSF leak at C1-C2 level and intracranial signs of SIH. The woman was treated with an autologous blood patch and recovered quickly. Focus on subjective symptoms and MRI findings seem to be important in the diagnostic procedure of SIH.
