Evaluation of Extrathyroid Masses of the Head and Neck With Gray Scale Ultrasound

Abstract

• The utility of gray scale ultrasonography in evaluation of extrathyroid masses of the head and neck is demonstrated by correlating ultrasonic data with clinical and histologic findings in 40 cases. This technique is valuable in differentiating cystic from noncystic masses in determining the nature of inflammatory masses, and in many cases allows determination of the margins of a mass and its relationship to ajacent structures.
