Abstract
Pneumatosis cystoides coli (PCC) is rare idiopathic disorder characterized by many cysts filled with air located in the colon wall in submucose or subserose layer. Any part of the colon can be affected, but the most affected region is it's left side.
Thanks to cooperation among departments we can present three cases with accidental finding PCC during colonoscopy. The diagnose was verified by virtual CT colonoscopy.
