Presentation
Increasing abdominal pain post right hemicolectomy for cancer.
Patient Data

Perforated sigmoid diverticulitis.
Case Discussion
An uncomplicated right hemicolectomy was performed because of a suspicious polyp discovered at colonoscopy. No nodal disease or metastasis and no local symptoms or obstruction.
4 days following the procedure, she complained of increasing abdominal pain and lower abdominal tenderness which developed into localized peritonitis.
CT was requested to rule out any collection or complication related to the surgery. Instead, it demonstrates acute inflammatory change around the sigmoid colon with diverticulitis with a localized perforation.
