title: Post-mortems in recreational scuba diver deaths: the utility of radiology.
abstract: Post-mortem radiology and autopsy findings in a series of six diving-related deaths are presented. The cases had different causes of death but essentially similar radiological findings. We propose that the so-called classical radiological features of cerebral arterial gas embolism more likely represent "off-gassing" (gas coming out of solution into intra-vascular spaces due to pressure changes). As such, we suggest that post-mortem radiology, when accompanying a competent autopsy examination, be limited to the chest, whereby it may be useful in the demonstration of pneumothoraces which might not be demonstrated at autopsy, thereby providing supporting evidence for barotrauma in the context of appropriate clinical and autopsy findings.
