Clinical and imaging features of idiopathic intracranial hypertension / 中南大学学报(医学版)

ABSTRACT

OBJECTIVES@#Idiopathic intracranial hypertension (IIH) is a syndrome that excludes secondary causes such as intracranial space-occupying lesion, hydrocephalus, cerebrovascular disease, and hypoxic ischemic encephalopathy. If not be treated promptly and effectively, IIH can cause severe, permanent vision disability and intractable, disabling headache. This study aims to explore the clinical and image features for IIH, to help clinicians to understand this disease, increase the diagnose rate, and improve the outcomes of patients.@*METHODS@#We retrospectively analyzed 15 cases of IIH that were admitted to Xiangya Hospital, Central South University, during January 2015 to September 2020. The diagnosis of IIH was based on the updated modified Dandy criteria. We analyzed clinical data of patients and did statistical analysis, including age, gender, height, weight, medical history, physical examination, auxiliary examination, treatment and outcome.@*RESULTS@#There were 10 females and 5 males. Female patients were 22 to 42 years old with median age of 39.5. Male patients were 27 to 52 years old with the median age of 44.0. The BMI was 24.14-34.17 (28.71±2.97) kg/m@*CONCLUSIONS@#IIH primarily affects women of childbearing age who are overweight. The major hazard of IIH is the severe and permanent visual loss. Typical image signs have high specificity in IIH diagnosis. Prompt diagnosis and effective treatment are significantly important to improve the outcomes of patients.
