Figure 10a. Abscess due to "dropped" appendicoliths in a 46-year-old woman who underwent laparoscopic appendectomy 2 months earlier. (a) Axial contrast-enhanced CT scan shows calcification (arrowhead) in the Morison pouch, a finding that represents dropped appendicoliths. (b) Axial contrast-enhanced CT scan obtained cephalad to a shows a cystic mass with wall enhancement (*). This appearance is consistent with an abscess in the posterior right subhepatic space.
