    Signs of intracranial hypertension (IH) detected by magnetic resonance imaging (MRI), such as empty sella (empty sella), increased cerebrospinal fluid (CSF), optic nerve tortuosity, and rhabdominal sinus stenosis (TVSS), usually associated with idiopathic Intracranial hypertension (IIH) is related, but it is also present in patients with primary headache syndrome and asymptomatic patients


    It is estimated that in the general patient population, the incidence of empty shells is between 8% and 35%, and it is more common in women and obese people


    Patients who have incidentally detected MRI signs of IH are often referred to a neurology or neuro-ophthalmology clinic, and often undergo invasive procedures, such as lumbar puncture, because they are worried about IIH


    He often undergoes invasive examination procedures, such as lumbar puncture, because he is worried about IIH


    diagnosis

    Between 2002 and 2016, the incidence of IIH in England doubled, the corresponding number of hospital admissions increased by 442%, and direct medical expenses increased by 6 times


    In this way, Benson S.


    From August 1, 2019 to March 31, 2020, they conducted this prospective cross-sectional study on outpatients who received brain MRI examinations at outpatient imaging institutions, and took pictures of fundus at the same time


    Main clinical outcomes: the prevalence of MRI signs of IH and the prevalence of nipple edema detected on fundus photographs


    A total of 388 patients underwent eligibility screening; 92 of them were excluded


    The most common indication of MRI is the monitoring of brain tumors (82 patients [27.


    Of the total 296 patients in the study, 98 patients (33.


    Six of the 198 patients (3.


    Compared with patients without papillary edema, patients with papillary edema have a significantly higher body mass index and IIH history.


    Compared with patients without nipple edema, patients with nipple edema had significantly higher body mass index and IIH history.


    The important significance of this study is that it found that: Magnetic resonance imaging signs of IH are common in patients undergoing brain MRI, but they are rarely related to nipple edema


    Magnetic resonance imaging signs of IH are common in patients undergoing brain MRI, but are rarely associated with papillary edema .
