Fig. 7B. Type 4 paraesophageal hernia in 49-year-old woman. Axial CT images
obtained with oral contrast material show entire stomach herniated
intrathoracically (gastric fundus [F], body [B], antrum [A]). Esophagus is
identified (arrows, A and B), and esophagogastric
junction is seen (arrow, C). Duodenal bulb is also
intrathoracic (asterisk, C). Lesser curvature is inferior to
greater curvature and anterior to esophagus, and gastric fundus is located to
left of and lateral to gastroesophageal junction. This indicates anterior
mesenteroaxial rotation with resulting upside-down stomach. Additionally,
there is herniation of transverse colon (arrowhead, C),
indicating type 4 hernia.
