CLINICAL AND RADIOLOGICAL PROFILE OF PATIENTS OF IDIOPATHIC INTRACRANIAL HYPERTENSION PATIENTS ATTENDING TERTIARY CARE HOSPITAL IN SOUTH INDIA

Abstract

Background: idiopathic intracranial hypertension (IIH) is one of the causes of headache presenting in tertiary hospital. However, there are only limited studies on IIH. : To study the clinical and radiological prole of IIH patients. hospital based observationalAim Setting and Design: descriptive study. Headache patients were admitted and evaluated in the department of Neurology (from April 2021 toMaterial and Methods: April 2022) detailed history, clinical examination, and neuroimaging, Cerebral spinal uid (CSF)routine analysis and manometry were done. After evaluation, diagnosed 32 cases of IIH by modied Dandy criteria and the secondary causes of raised intracranial pressure and primary ocular pathology were excluded. Entire study population were females. The mean age was 30 years. 16 (50%) cases were obese, 9 overweightResults: and normal BMI were seven. All case has Headache, bifrontal headache was very common rather than occipital as presentation. Bilateral papilledema seen in all except one case of secondary optic atrophy with equivalent nding in Optical Coherent tomography. CSF analysis was normal and CSF pressure was elevated(≥250mmg) in all cases. Empty Sella was the most common radiological nding (26/32; 81.25%). Conclusion: IIH typically affects females of childbearing age group, mostly obese. However, it is not uncommon in the nonobese female as seen in the present study. In Indian subcontinent overweight and obesity may not be a dominant risk factor for the development of IIH. Cases with normal BMI with clinical features of raised intracranial pressure, refractory headache, visual symptoms and normal neuroimaging or empty Sella on MRI should be evaluated for IIH
