Fig. 14. Intramural gas in GI tract unassociated with CPR in 72-year-old deceased woman who did not undergo CPR (case 16).

CT scan obtained 1 hour and 48 minutes after death shows intramural gas throughout GI tract (arrows) similar to case 15. CPR was not performed before death due to patient's DNR order. However, autopsy did not reveal any pathology associated with this postmortem CT finding. Therefore, intramural gas was attributed to mucosal injury, which is normal postmortem change. CPR = cardiopulmonary resuscitation, CT = computed tomography, DNR = do-not-resuscitate, GI = gastrointestinal
