Vascular anomalies of the head and neck.

The head and neck are the most common site of involvement for vascular tumors and malformations, with more than half of all vascular anomalies seen in this region. Lesions in this location can cause significant disfigurement and can be associated with airway obstruction, impairment in vision or hearing, swallowing disorders and hemorrhage. Accurate diagnosis is critical in determining treatment, and interdisciplinary care is essential for optimal management. We review clinical and imaging features that are key to establishing the correct diagnosis, and review treatment modalities, with emphasis on interventional and surgical procedures.
