1) Describe the sonographic technique of evaluating hernias. 2) Identify sonographic features which help differentiate epigastric, direct, indirect and femoral hernias. 3) Understand some of the common pitfalls when using sonography to evaluate patients with inguinal hernias.
Inguinal hernias are a common clinical condition which may present with inguinal discomfort, and Ultrasound is a useful means for making a definite diagnosis. Ultrasound is most helpful in diagnosing Subtle hernias which are often difficult to diagnose clinically. Understanding the sonographic anatomy of the inguinal canal and femoral triangle and dynamic evaluation using valsalva, is the key to diagnosing different types of inguinal hernias. However, there are a number of concepts which help the practitioner maximize the utility of the technique, including understanding the relationship between the deep ring and the inferior epigastric artery, and being aware of the pitfalls like the "thin man" pitfall and the normal movement of the spermatic cord, to name a few.
