A four-year-old child with a large left axillary occupancy was considered to have a cavernous hemangioma. MRA suggested that the posterior wall of the tumor was in close proximity to the blood vessels. Song Yan of the Department of Vascular Surgery of the First Affiliated Hospital of Zhengzhou University performed a complete resection up to the root of the axilla and down to the surface of the axillary vein. After resection, the arteriovenous nerve “skeletonization” was revealed. There was no abnormality in the sensory movement of the limb.
