Pneumatosis intestinalis often remains asymptomatic in most cases but may clinically present in a benign form or less frequently in fulminant forms. Treatment for such conditions includes antibiotic therapy diet therapy oxygen therapy and surgery. Case presentation The present report describes the case of a 56-year-old Swiss-born man with symptomatic pneumatosis intestinalis resistant to all treatment except hyperbaric oxygen therapy as showed by computed tomography colonography images performed before during and after treatment. Conclusions The current case describes the response to hyperbaric oxygen therapy using virtual colonoscopy technique one month and three months after treatment. Moreover after six months of follow-up there has been no recurrence of digestive symptoms. Introduction Pneumatosis intestinalis PI is a condition in which submucosal or subserosal gas cysts are found in the wall of the small or large bowel 1 . PI may affect any segment of the gastrointestinal tract. The pathogenesis of PI is not understood but many different causes of pneumatosis cystoides intestinalis have been proposed including mechanical and bacterial causes 2 . Whatever the pathogenesis gas forming bacteria gain access to the submucosa through breaches in the mucosa and once inside the bowel wall gas may spread along the bowel and mesentery to remote sites. In most cases PI is an incidental finding whereas in others PI is secondary to a wide variety of gastrointestinal and .
