We present a case of massive epistaxis caused by an internal carotid artery aneurysm. The initial treatment with endovascular balloon embolization failed as a result of balloon displacement. After rebleeding, the intracavernous aneurysm was treated with an endovascular detachable balloon embolization technique, which resulted in cessation of epistaxis. The different treatment options for interventional radiology and management of ruptured carotid artery aneurysms are discussed.
