Pneumatosis cystoides intestinalis (PCI) is an uncommon condition in which submucosal or subserosal gas cysts are present within the bowel wall. We report a case of a 37-year-old man with no medical history. He underwent a colonoscopy for screening purposes, which revealed multiple and variably sized submucosal tumors in the ascending colon. Endoscopic ultrasonographic (EUS) finding showed multiple hyperechogenic regions with distal acoustic shadowing within the submucosa of the ascending colon. A computed tomography scan showed multiple air-filled cystic masses in the ascending colon. EUS appears to be effective for the diagnosis of PCI.
