Portomesenteric vein gas and pneumatosis intestinalis--a rare complication after neoadjuvant radiochemotherapy in oesophageal cancer

Portomesenteric vein gas and pneumatosis intestinalis is most commonly caused by mesenteric ischemia and bowel necrosis but may have a variety of other causes. The etiology is multifactorial and the clinical presentation is variable. The diagnosis is based on a combination of clinical suspicion and radiographic findings. The finding of hepatic portal venous gas alone is not an indication for emergent exploration. We report portomesenteric venous gas as a rare complication after neoadjuvant radiochemotherapy of the oesophageal cancer (Fig. 3, Ref. 12).
