We describe the case of a 35-year-old man who had suffered a severe multi-t
rauma with blunt thoracic injury, left scapula and humerus fractures 5 year
s earlier. At the time of the trauma, a diaphragmatic lesion went unnoticed
. Five years later, the patient had a 24-h history of increasingly severe a
bdominal pain with repeated vomiting. Helical CT showed a portion of the le
ft hemidiaphragm avulsed from its insertions on the ribs with large-bowel l
oop obstruction herniated in the left hemithorax. The preoperative CT diagn
osis was confirmed by surgery: reduction of the hernia and reinsertion of t
he hemidiaphragm to the lumbocostal arch were performed.
