Usefulness of contrast-enhanced ultrasound in the diagnosis of neck cavernous hemangioma in adults.

It is often difficult to diagnose in time because conventional medical imaging examinations usually fail to provide valid information. Clinicians should attach importance to the value of contrast-enhanced ultrasound as an adjunct to rapidly diagnose cavernous hemangioma.
