You are correct. CT shows a hiatal hernia that has undergone rotation to cause a gastric volvulus. The 2 chambers in the mediastinum represent the stomach fundus and body. After laparoscopic reduction of her mesentero-axial gastric volvulus, she required ICU support and another gastroscopy to correct bleeding from a duodenal ulcer, and was discharged 2 weeks later.
