Reversible cerebral vasoconstriction, internal carotid artery dissection and renal artery stenosis

It has been described in association with multiple disorders, but has only been reported rarely in the setting of carotid artery dissection and, to our knowledge, never before in association with renal artery stenosis.DK Field, TJ Kleinig, PD Thompson and TE Kimbe
