Abstract
- Recently with the development of magnetic resonance imaging(MRI) techniques, many reports of radiologic findings in spontaneous intracranial hypotension(SIH) have been reported. However in our review, the pachymeningeal changes within spinal canal secondary to SIH are not reported. In SIH, same mechanisms of it might act in the intraspinal space, which cause pachymeningeal changes of spinal dura and clinical features of spinal involvement. We reports four cases of SIH, in which MRI of the brain and spine reveals diffuse symmetric pachymeningeal enhancement. This is the first report of the spinal images in SIH.
