Ultrasound report of appendicitis: a. It depends on the size of the appendix. The normal human appendix is about 5-10 cm long and 0.5-0.7 cm in diameter, and its length as well as diameter may vary slightly from one appendix to another, but the fluctuation range is not too big. If the patient’s appendix is enlarged or thick, the inflammation of the appendix is heavy. The appendix is located at the root of the cecum and is attached to the posterior medial wall of the cecum, but some patients have appendicitis in the pelvic position, and some patients have appendicitis in the posterior position of the cecum. Third, we should see if the ultrasound report of appendicitis of the patient describes the possibility of forming a mass in the right lower abdomen of the patient. If the patient forms a periappendiceal abscess in the right lower abdomen, it usually describes the formation of a mass around the appendix, so do not rush to the surgical treatment at this time.
