Magnetic Resonance Imaging of Intracranial Hypotension Syndrome With Pathophysiological Correlation

Abstract

In the brain, diffuse dural-arachnoid enhancement is the most common imaging abnormality and is probably the earliest magnetic resonance manifestation of intracranial hypotension syndrome, while subdural fluid collections and descent of the brain are indicators of a more severe hypotensive state. Extra-arachnoid fluid collections are common spinal imaging abnormalities.
