Welcome to the ePoster Viewing Panel of AICOG 2025

Introduction: Idiopathic Intracranial Hypertension (IIH) is a neurological condition with a benign course characterised by raised intracranial pressure of unknown etiology. It can appear in any trimester and has no impact on evolution of pregnancy. Formerly called as Pseudotumor cerebri, predominately affects women of reproductive age with obesity. Aim: To present multidisciplinary management strategy of Idiopathic intracranial hypertension in pregnancy. Materials and Methods: Complete assessment of visual function including visual fields, OCT imaging, RFNL screening, CSF analysis from lumbar puncture, MRI Brain with MR Venogram, Serum Lipid profile and basic blood panel. Case summary: A 22 year old Primigravida with normal BMI (24.1Kg/m2) conceived by ovulation induction, hypothyroid developed complaints of severe generalized headache accompanied by photophobia, neck and back pain, vomiting and tinnitus in her 2nd trimester. There were no localized findings on neurological examination. Evaluation of fundus revealed severe bilateral papilledema. MRI found no structural or vascular lesion. Lumbar puncture was done, CSF manometry showed pressure of 34cmH2O. CSF analysis was normal, no growth noted. Patient was on T.Acetazolamide 250mg BD from 26 weeks. Serial monitoring by OCT was done. The weight gain throughout pregnancy was 10kg. At 38+6 weeks of gestation, she went into spontaneous labour, her second stage was cut short and delivered a girl baby weighing 2.7kg with an excellent APGAR. Key Words: Idiopathic intracranial hypertension, Papilledema, Acetazolamide, Weight gain. Concluding remarks: It is a diagnosis of exclusion. Mode of delivery in IIH based on patient?s visual prognosis is brought into play. References: 1. Chazal J, Klein O. Benign Intracranial Hypertension:history, definition and pathophysiology.
