Spontaneous Intracranial Hypotension: A Review of Neuroimaging and Current Concepts

Abstract Spontaneous intracranial hypotension (SICH) is the emerging cause of orthostatic headache as it has been better recognized in recent years. SICH happens due to spinal cerebrospinal fluid (CSF) leak; however, manifestations are predominantly cranial and hence imaging includes brain spine. There few characteristic features be concerned about diagnose patients with vague symptoms or low clinical suspicion. Spine screening recommended these assess CSF leaks. While neuroradiologists play a significant role from time diagnosis treatment SICH, there need for all general radiologists aware condition. Computed tomography myelogram digital subtraction performed diagnostic therapeutic management SICH. known risk recurrence sagittal longitudinal epidural collection hence, targeted blood patch should used instead blind patch. Most importantly, slow mobilization following avoid recurrence.
