title: Imaging of vascular lesions of the head and neck.
abstract: The diagnosis of vascular lesions of the head and neck should be directed by classifying the lesions as tumors or malformations and by determining their flow characteristics. Location of the lesion is key when differentiating between vascular neoplasms. Ultrasonography is an appropriate screening tool; MRI is often used to confirm the diagnosis. Computed tomography can be used for further characterization of the lesion, particularly when there is bony involvement. In many cases, vascular lesions grow to be extensive. In these cases, percutaneous sclerotherapy or embolization therapy can be employed to aid in surgical resection.
