Appendiceal mucocele is a rather rare entity mimicking acute appendicitis, ranging from simple cystadenoma to malignant adenocarcinoma. Depending on radiological diagnosis, treatment varies from simple appendectomy to right hemicolectomy. Moreover complications in case of malignancy such as pseudomyxoma peritonei can be avoided if early diagnosis is obtained. Typically US appearance includes onion skin sign and on CT lack of uptake is considered in favour of a benign case. Contrast Enhanced Ultrasound is applied in order to investigate nodule uptake indicative of malignancy.
