We report an 8-year-old female who developed left abducens nerve palsy and progressively enlarging left internal carotid aneurysm in the setting of sphenoid sinusitis. Despite conservative management with antibiotics and antiplatelet agent, she developed enlargement of the aneurysm with embolic stroke. For that reason, she underwent occlusion of her left internal carotid artery with coiling, after confirmation of good collateral circulation. The patient tolerated the procedure well, with improvement of her symptoms. To our knowledge, this is the first report documenting good neurological outcome after elective internal carotid occlusion. Due to lack of guidelines, management of aneurysms secondary to infection should be individualized, based on collateral circulation and risk of intervention.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
