Recurrent spontaneous intracranial hypotension in early pregnancy.

Spontaneous intracranial hypotension (SIH) is an uncommon condition characterised by postural headache secondary to low cerebrospinal fluid pressure. Here we present a case of recurrence of SIH in early pregnancy in a 26-year-old woman. She first presented at the age of 21 years at 15 weeks' gestation with a history of headache, nausea, vomiting, neck stiffness and photophobia. Findings from a MRI brain scan led to a diagnosis of SIH. She was treated with autologous epidural blood patching and remained asymptomatic until her second pregnancy 5 years later, when she re-presented at 16 weeks' gestation with similar symptoms. She was again diagnosed with SIH and required a repeat treatment of autologous epidural blood patching. She subsequently remained symptom free and delivered a healthy boy at term.
