The most common symptom is pain or a palpable mass in the right lower quadrant on physical examination. The preoperative diagnosis is performed with abdominal U.S. and confirmed with CT scan; typical CT scan image is a capsulated cystic mass with calcification of the wall while U.S. pattern shows cystic lesion with the onion skin sign considered a specific sonographic marker for appendiceal mucocele.
