“…The coiled spring appearance on the barium enema probably corresponds to the concentric ring sign on ultrasound. Similar to the coiled spring sign of appendiceal intussusception on the barium enema, the sonographic coiled spring sign will also be seen in acute appendicitis [12].…”

A case in which appendiceal intussusception was diagnosed preoperatively by sonography is described. The sonographic finding of multiple concentric hypoechoic and hyperechoic rings was confirmed at laparotomy to be due to appendiceal intussusception. Demonstration of the sonographic coiled spring sign in the right lower quadrant should raise the possibility of appendiceal intussusception. The differential diagnosis is discussed.

CT diagnosis of appendiceal intussusception in a middle-aged female

Appendiceal intussusception is rare with an estimated incidence of 0.01%. Although it is infrequently encountered, the few documented cases of this entity have shown it may mimic or indicate an underlying neoplasm when evaluated with colonoscopy. With the abundant use of multi-detector CT and increased utility of CT colonography, awareness of the radiologic findings of this condition has become increasingly important. Appendiceal intussusception, while potentially pathologic in its own right, may mimic or even coexist with other pathologies, both malignant and benign. We present a case of adult appendiceal intussusception without a "lead point" that was successfully diagnosed by CT imaging.
