Case report: gastric ischemia, a fatal disease of gastric pneumatosis
BACKGROUND Gastric pneumatosis indicates the presence of air within the stomach wall. The etiologies included gastric ischemia, gastric intramural infection, gastric mucosal disruption, and secondary to pneumomediastinum. Gastric ischemia is rare because of the rich collateral blood supply to the stomach.
CASE PRESENTATION An 82-year-old man presented to the emergency department with a 2-day history of epigastric fullness, following by fever and low blood pressure. Chest X-ray and abdominal computed tomography revealed gastric pneumatosis at the gastric fundus. The esophagogastroduodenoscopy confirmed the ischemic change of mucosa at the gastric fundus. After antibiotics and medical management, the patient became better and was eventually discharged.
CONCLUSION For the diagnosis of gastric ischemia, physicians should be alert to the hints of gastric pneumatosis from X-ray and computed tomography. It is important to distinguish between gastric ischemia and the other causes of gastric pneumatosis to judge clinical management.
