Imaging findings post colorectal endoscopic mucosal resection.

Endoscopic mucosal resection is commonly the treatment regime of choice for large sessile colonic polyps. We describe the computed tomography findings of a 51 year old female who presented with transient severe abdominal pain without systemic upset post endoscopic mucosal polyp resection, which resolved with conservative management. This is the second case in the literature that demonstrates 'normal' appearances post endoscopic mucosal resection. The clinical team and radiologist need to be aware of these findings when making management decisions in patients who present with acute pain post endoscopic mucosal resection.
