Does "chronic" appendicitis actually exist? and would it be seen on ultrasound. appendix type pain 5 days. normal wbc and us.

The existence of: "chronic appendicitis" is controversial. Ultrasound is very good at evaluating the appendix if the appendix can be definitively located. Unfortunately, it may be difficult to visualize the appendix in large or gassy patients, and the appendix also has variable anatomic locations, so ultrasound may be inconclusive. CT more reliably demonstrates the appendix.
