title: Mucosal pseudolipomatosis: an air pressure-related colonoscopy complication.
abstract: Mucosal pseudolipomatosis is a recently described colonoscopic finding, most likely caused by intramucosal air. We describe four asymptomatic patients with this lesion which completely resolved 3 weeks later on repeat colonoscopy. This is a benign, transient lesion with distinct endoscopic and histologic findings. The similarity between mucosal pseudolipomatosis and pneumatosis cystoides intestinalis is supportive of the mechanical theory for pneumatosis cystoides intestinalis.
