title: Presentations of agenesis of the hemidiaphragm in an adult.
abstract: A 67-year-old man presented with chest tightness and vomiting of one-week duration. On physical examination bowel sounds were heard on the left chest. Plain chest x-ray, barium swallow, and CT scan suggested gastric volvulus with diaphragmatic hernia. At laparotomy there was complete agenesis of the left hemidiaphragm with no diaphragmatic remnants seen and no associated lung hypoplasia. This is an extremely rare condition and careful assessment is needed to differentiate between diaphragmatic hernia and agenesis of the diaphragm as more cases could be diagnosed in the future as a result of good perinatal care of agenesis of hemidiaphragm AHD and long term survival to adulthood.
