We present 2 cases of intussusception of the appendix vermiformis (IAV) in children. Sonographic examination demonstrated a lead point within a characteristic multiconcentric ring sign, and longitudinal sonograms showed the inverted appendix protruding into the cecal lumen. A contrast‐enema study, using a water‐soluble contrast medium, was performed in each case, and a “coiled‐spring” sign or “spiral shell” appearance confirmed the diagnosis. A surgical reduction of the appendix and an appendectomy were performed in each case. © 2000 John Wiley & Sons, Inc. J Clin Ultrasound 28:492–496, 2000.
