Sign Up to like & getrecommendations! Published in 2024 at "American Journal of Neuroradiology"
DOI: 10.3174/ajnr.a8173
Abstract: BACKGROUND AND PURPOSE: Spontaneous intracranial hypotension is an increasingly recognized condition. Spontaneous intracranial hypotension is caused by a CSF leak, which is commonly related to a CSF-venous fistula. In patients with spontaneous intracranial hypotension, multiple… read more here.
