title: Ultrasonic analysis of head and neck neoplasms. Correlation with surgical findings.
abstract: Ultrasonography of head and neck neoplasms is useful in the preoperative evaluation of patients. Inflammatory masses demonstrate high reflectivity in a homogeneous pattern and have diffuse borders. Similarly, lipomas show medium to high reflectivity and have a homogeneous pattern, but are well outlined. Mixed tumors of the major salivary glands have a characteristic heterogeneous pattern and are well outlined. Malignant lesions demonstrate low reflectivity in a homogeneous or heterogeneous pattern and have poorly outlined or diffuse borders. Cysts of the head and neck are well outlined and devoid of interior echoes.
