[edit] Discussion of Hiatal hernia

  • Hiatal hernias are classified as:
    • Sliding hiatal hernia
    • Paraesophageal hernia


  • Sliding hiatal hernia


  • Paraesophageal hernia
    • The gastroesophageal junction is inferior to the diaphragm, but the fundus and sometimes the whole stomach have migrated alongside the esophagus into the mediastinum.
    • Paraesophageal hernia is considered to be a potentially life-threatening condition because of the risk of gastric volvulus, incarceration, or strangulation of the hernia

[edit] Imaging Findings of Hiatal hernia

  • On chest radiographs, a paraesophageal hernia may appear as a soft-tissue-opacity lesion posterior to the heart near the esophageal hiatus.
  • CT helps verify migration of the stomach cranially through the hiatus. Sagittal and coronal reformatted images often help demonstrate the hernia and the hiatal defect.
