Case Discussion
This is a classic case of perforated appendicitis. Within the proximal/mid appendix there is an appendicolith. Just beyond the appendicolith, the appendix becomes dilated, irregular, and fluid-filled. Along the anterior margin there is a site of discontinuous mucosal enhancement with adjacent phlegmon, consistent with perforation. No other organized or drainable fluid collections are present.
