Bottom Line: Computed tomography (CT) is widely used in postmortem investigations as an adjunct to the traditional autopsy in forensic medicine.However, on interpretation, postmortem CT findings that are seemingly due to normal postmortem changes initially, may not have been mere postmortem artifacts.In this pictorial essay, we describe the common postmortem CT findings in cases of atraumatic in-hospital death and describe the diagnostic pitfalls of normal postmortem changes that can mimic real pathologic lesions.

ABSTRACT
Computed tomography (CT) is widely used in postmortem investigations as an adjunct to the traditional autopsy in forensic medicine. To date, several studies have described postmortem CT findings as being caused by normal postmortem changes. However, on interpretation, postmortem CT findings that are seemingly due to normal postmortem changes initially, may not have been mere postmortem artifacts. In this pictorial essay, we describe the common postmortem CT findings in cases of atraumatic in-hospital death and describe the diagnostic pitfalls of normal postmortem changes that can mimic real pathologic lesions.

Intraluminal gas in GI tract unassociated with CPR in 64-year-old deceased man (case 14).CT scan obtained 3 hours and 57 minutes after death shows widespread distension of GI tract. Although this finding can be caused by CPR, in this patient, CPR was not performed due to DNR order. This finding is considered nonspecific. CPR = cardiopulmonary resuscitation, CT = computed tomography, DNR = do-not-resuscitate, GI = gastrointestinal

Figure 12: Intraluminal gas in GI tract unassociated with CPR in 64-year-old deceased man (case 14).CT scan obtained 3 hours and 57 minutes after death shows widespread distension of GI tract. Although this finding can be caused by CPR, in this patient, CPR was not performed due to DNR order. This finding is considered nonspecific. CPR = cardiopulmonary resuscitation, CT = computed tomography, DNR = do-not-resuscitate, GI = gastrointestinal

Mentions: In case 14, CPR was not performed because of the patient's DNR order. Although GI distension was observed on postmortem CT (Fig. 12), this finding is not always associated with CPR and may occasionally be observed in patients who do not receive CPR. The source of the massive gas volume in this case was unclear, and the finding is nonspecific. However, postmortem CT images with this abnormality require careful interpretation because GI dilatation on postmortem CT in a patient who does not receive CPR may indicate a bowel obstruction caused by a tumor, feces, volvulus, or other condition.
