Abstract
An 82-year-old woman with cerebral infarction-mediated dysphagia was referred to our hospital in order to place a percutaneous endoscopic gastrostomy (PEG). As the pre-PEG evaluation, we performed transnasal endoscopy which did not show any gross lesion in the esophagus, stomach or duodenal bulb. Immediately after the endoscopy, following gas insufflation of the stomach, simple abdominal CT was performed. The CT imaging revealed pneumatosis cystoides intestinalis (PCI) with intraperitoneal free gas. The PCI disappeared with conservative treatments without producing clinically significant symptoms. A case report is presented herein on a PCI which developed following esophagogastroduodenoscopy withoutother causative concomitant GI diseases.
