Injury to the diaphragm is a marker of severe trauma yet remains one of the
most misdiagnosed traumatic lesions. The mechanism may be penetrating (sta
b or gunshot wounds) or blunt (high velocity injuries). Rupture of the diap
hragm may be overlooked due to common associated injuries. Diagnosis is bas
ed on strong clinical suspicion and repeated chest x-rays. Current diagnost
ic tools include CT scan and minimally invasive surgical techniques (laparo
scopy or thoracoscopy) in stable patients. These relatively new methods cou
ld provide more accurate diagnosis. The main feature of diaphragmatic injur
y is the incidence of late presentation with the possibility of life-threat
ening complications such as strangulations may even occur late.
