The cavernous hemangioma is a benign vascular neoformation of congenital origin, characterizing by the formation of large vascular spaces filled with blood. The case reported in this study differentiates itself from other cases of hemangiomas, not only because of the magnitude of the tumor and the vascular compromise, but also due to the time of permanence that this tumor was lodged since she was 10. The treatment for this type of injury varies with the size and risk of a rupture of the hemangioma, and with the symptoms of the patient. Surgical resection, artery embolization, surgical enucleation and radiotherapy can be chosen by the doctor as alternatives for the treatment. The rarity and complexity of this case, added to the difficulty of treatment found by the patient during those 20 years of tumor development, compose the factors that corroborated to the presentation of this case.
