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 cervical mass. This mass had the sonographic properties of air; it communicated with and extended the piriform sinus as well as deformed the left lamina of the thyroid cartilage. A preliminary diagnosis of left pharyngocele was confirmed by CT. To our knowledge, this is the first sonographic description of such an abnormality. Copyright 2000 John Wiley & Sons, Inc.
