Diagnostic Value of MRI and MRV in Migraine indicating Intracranial Hypertension

Abstract

Background: Migraine is one of the most common causes of headaches. Its mechanism and pathophysiology are complex and linked to environmental and genetic factors. and it is more prevalent in women post-pubertal. Sometimes migraine is associated with intracranial hypertension. MRI and MRV are non-invasive techniques to detect intracranial hypertension rather than opening CSF pressure. Objectives: This study is to investigate the role of MRI and MRV in detecting increased intracranial tension in patients suffering from migraine. Patients and methods: This cross-sectional study was conducted in Qena University Hospital (Radiology & Neuropsychiatry departments). South valley university between March 2022 till March 2023. This study was conducted on 50 cases of migraine patients by detecting signs of increase intracranial pressure by MRI and MRV and comparing results with opening CSF pressure. Results: The migraine patients were divided into two groups regarding C.S.F pressure. There was a statistically significant difference between the two groups regarding papilledema (P < 0.001) and transverse sinus stenosis grades (P =0.032). By logistic regression analysis, the significant predictors of high C.S.F were papilledema and grade II transverse sinus stenosis (P =0.014, and 0.033, respectively). Conclusion: MRI and MR venography can be used in detecting intracranial hypertension in migraine patients. The most contributing factors for intracranial hypertension among migraine patients were papilledema and grade II TSS.
