Key Words: Trauma Right Diaphragm
We read with interest the article by Turhan et al. about traumatic diaphragmatic rupture, especially their experience with right-sided ruptures [1]. We did report a case of late presentation of traumatic rupture of the right hemidiaphragm, which is more difficult to detect than left-sided injuries [2]. We cannot but fully agree with their conclusion that a high index of suspicion is of utmost importance for the diagnosis of this condition in any patient with thoracoabdominal injury. However, we would like to emphasise that this is even moreso in suspected right-sided injuries, when early diagnosis is difficult. The chest X-ray could be normal or show only slight elevation of the right hemidiaphragm, as was in our case. Magnetic resonance imaging has been shown to be very useful in establishing the diagnosis because of its capability of directly acquiring coronal and sagittal images allowing evaluation of the entire diaphragm. The disadvantage is that it cannot be easily carried out in an emergency situation, when helical CT remains the modality of choice [3].
We would also like to add that the same high index of suspicion should be held when dealing with post trauma patients who complain of persistent right-sided chest discomfort for many weeks post trauma. Diagnosis can remain elusive. In fact, in our case where the discomfort persisted for up to twenty-one weeks post trauma, even helical CT scan was only suggestive and confirmation was only achieved at operation, at which the diaphragmatic tear was repaired via the transthoracic approach. A persistently elevated right hemidiaphragm on routine radiography must arouse suspicion and lead to more investigations to rule out the condition.
