Role Of Mri In Diagnostic Evaluation Of Bih

ABSTRACT

Objective:To study the role of Magnetic Resonance Imaging in diagnostic evaluation of benign intracranial hypertension (BIH).Materials and methods:The present study was carried out in the Department of Radiodiagnosis, ESIC Medical College & Hospital, Faridabad. The study included twenty seven patients who were diagnosed with benign intracranial hypertension(BIH) based on modified Dandy's criteria.Results:Middle aged females were more commonly affected. Most common radiological findings were slit like frontal horns of lateral ventricles and empty sella, present in all of our patients. Findings involving optic nerve were present in 13 out of 27 (48%) of our patients, while 2 of 27 (7%) patients had spontaneous csf leak in presence of BIH. On manometry, CSF opening pressure[OP] was more than 25cm of H2O in all the patients.Conclusion:Slit like ventricles, empty sella, vertical kinking of optic nerve and distension of the perioptic subarachnoid space are important radiological markers of BIH that contribute to its diagnosis
