[Pneumonia following bronchography]

The extravasation of contrast medium into the alveoli during or following bronchography would appear to be associated with an increased complication rate. The histomorphological changes occurRing may vary in degree, and it may thus be difficult to differentiate such changes from those associated with other forms of pneumonia and pneumoconiosis. This paper reports on a case in which, using energy-dispersive X-ray micro-analysis in the scanning electron microscope, the presence of contrast medium within a region of alveolar pneumonia was observed, thus enabling accurate establishment of the cause of this condition.
