Idiopathic Intracranial Hypertension in a Woman Carrying a Post-Term Pregnancy: A Case Report

We report the case of a 27-year-old primigravida with no particular history whose pregnancy was complicated, from the first trimester (13 weeks), by idiopathic intracranial hypertension (ICH) with visual impairment, for which she received medical care with depleting lumbar punctures without obstetric consequences. The objective of this work is to clarify the particularities of the delivery route in a woman carrying a pregnancy with post-term in a context of idiopathic ICH. This nosological entity would be linked to a defect in reabsorption of cerebrospinal fluid (CSF) at the level of arachnoid granulations. The main risk factors mentioned are: obesity, polycystic ovary syndrome, thrombophilia and hyperfibrinolysis. The diagnosis is based on the modified Dandy criteria after a negative clinical, biological and radiological investigation. The visual prognosis is compromised without directly endangering the life prognosis, which requires emergency treatment to preserve visual function. Furthermore, this disease does not affect the progress of the pregnancy.
