Sonographic discovery of a pharyngocele

Cervical sonography was performed in a 25-year-old man who was referred to our department because of the recent appearance of a left anterolateral cer vical mass. This mass had the sonographic properties of air; it communicate d with and extended the piriform sinus as well as deformed the left lamina of the thyroid cartilage. A preliminary diagosis of left pharyngocele was c onfirmed by CT. To our knowledge, this is the first sonographic description of such an abnormality. (C) 2000 John Wiley & Sons, Inc.
