Diaphragm function was graded by a senior radiology resident, as either “paralyzed” or “non-paralyzed,” based on appearance/shape of elevated hemidiaphragm on PA and lateral radiograph. The diaphragm position and shape for all patients were determined using measurements relating to skeletal structures and radius of curvature, respectively.

Diaphragmatic eventration is a thinning of a portion or all of the diaphragm where muscle has been replaced by fibroelastic tissue. It is prudent that the clinician recognizes this condition so that appropriate evaluation and treatment can be instituted.
