Abstract

Spontaneous Intracranial Hypotension(SIH) is a rare syndrome of spontaneous postural cephalalgia associated with low CSF pressure and usually without evidence of CSF leakage from meningeal defect due to dural puncture. The postural headache may appear suddenly or gradually and disappear within several weeks spontaneously. MRI findings maybe include diffuse symmetric pachymeningeal gadolinium-enhancement, also subdural effusion and downward brain displacement. We report two cases of SIH in which MRI of the brain reveals diffuse symmetric pachyme-ningeal enhancement.
