- young boys presenting with epistaxis
- vascular hamartoma
- embolization is therapeutic
- found at the bifurcation of the carotid artery where they splay its internal and external branches
- prolonged, intense tumor blush
- resectability depends on angle between ICA and ECA
- patients often left with hoarseness due to proximity of vagus nerve
- preoperative embolization may be considered
- highly vascular extra-axial neoplasm
- core is supplied by branches of the ECA while periphery is supplied by the ICA
- "spoke wheel" appearance on angiogram
- resection is usually curative
- large tumors may be embolized prior to resection
