Mucocèles appendiculaires, pseudomyxomes péritonéaux et tumeurs mucosécrétantes du carrefour iléocæcal : apport de l'imagerie dans la stratégie thérapeutique et le choix de la voie d'abord laparoscopique ou classique

The overall sensitivity of computed tomography (CT) for all the criteria studied was 93%. The predictive value for AM rupture of visualization of thick calcifications was 100%. On the other hand, rupture never occurred when the CT showed an AM under pressure, with thin walls and septa. The predictive value for PMP of “scalloping” was 100%. The diagnostic accuracy of the initial reading was 25/27 for the imaging overall and 25/25 for the CT. Preoperative visualization of the exact size of the intact AM or of diagnostic information about ruptured AM and PMP helped to select an appropriate approach in 25 of 27 cases.
