This usually high-flow vascular malformation may also present with potentially life-threatening, spontaneous, or tooth extraction-induced, hemorrhagic shock."

Lesions may be asymptomatic or may manifest with pain, ulceration, pulsation, tinnitus, minor bleeding or potentially life-threatening hemorrhage, blurred vision, impaired hearing, headache, paresthesia, enlargement of facial bones with intraosseous lesions, intraosseous hemangiomas, and speech, breathing and swallowing difficulties, as well as neuropathy."
