Colonoscopic polypectomy is a routine procedure with the potential for rare but well-known complications, including perforation and bleeding. Post-polypectomy electrocoagulation syndrome (PPES) is a less recognized cause of abdominal pain following this procedure. However, it is important to diagnose PPES in order to avoid unnecessary intervention. We present the case of a patient with abdominal pain after polypectomy. The patient underwent an unnecessary diagnostic laparoscopy on the basis of misinterpreted radiological findings. Her CT scan demonstrated the "donut" sign that was suggestive of ileocaecal intussusception. This case highlights the importance of recognizing PPES as a possible cause for abdominal pain after colonoscopic polypectomy and that it may also present with a "pseudodonut" sign on CT scan. It also demonstrates the importance of communicating and then integrating full clinical details with radiological findings when formulating a differential diagnosis.
