Chronic subdural haematoma associated with pre-eclampsia: case report and review of the literature.

Pre-eclampsia complicates approximately 5-8% of all pregnancies and may have adverse long-term effects on both mother and child. Chronic atraumatic subdural haematoma as a complication of severe pre-eclampsia, in the absence of clotting factor abnormalities, is a very rare condition. We present the case of a 30-year-old Moroccan woman who had a pregnancy 10 years previously, with an uneventful delivery. She presented with pre-eclampsia complicating a 29-week-old pregnancy. A few days preceding maternity unit admission the patient complained of headaches and malaise. Her blood pressure at admission was 150/120mmHg and subsequently was treated with doses of methyldopa and magnesium sulphate. Her condition worsened with a loss of consciousness 24 hours later and was transferred to the neurosurgical unit. A brain computerized tomography (CT) scan revealed a left-sided subdural haematoma and the patient underwent surgery, with a good postoperative outcome. This article highlights the occurrence of neurological complications due to pre-eclampsia/eclampsia that require particular neurosurgical attention, its treatment and prognosis. We also review the literature regarding this pathology.
