Mycotic intracranial aneurysms are infectious aneurysms accounting for 0.7%–6.5% of
all intracranial aneurysms and are most commonly located in distal branches of the
middle cerebral arteries, particularly at the bifurcation area. They are caused by
weakening of the vessel wall secondary to infection of a segment of the artery that
can be endovascular as in infective endocarditis or extravascular as in meningitis
or cavernous sinus thrombophlebitis. The rare occurrence of the mycotic cavernous
internal carotid artery aneurysm, its variable clinical picture and limited knowledge
of its natural course is a challenge for both diagnosis and management.
