Common Postmortem Computed Tomography Findings Following Atraumatic Death: Differentiation between Normal Postmortem Changes and Pathologic Lesions.

Ishida M, Gonoi W, Okuma H, Shirota G, Shintani Y, Abe H, Takazawa Y, Fukayama M, Ohtomo K - Korean J Radiol (2015)

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.

Hyperdense lung lesion not attributed to normal postmortem change in 18-year-old deceased man (case 8).CT scan obtained 3 hours and 32 minutes after death shows multiple areas of consolidation and randomly distributed nodules. Subsequent autopsy revealed pneumonia. CT = computed tomography

Figure 6: Hyperdense lung lesion not attributed to normal postmortem change in 18-year-old deceased man (case 8).CT scan obtained 3 hours and 32 minutes after death shows multiple areas of consolidation and randomly distributed nodules. Subsequent autopsy revealed pneumonia. CT = computed tomography

Mentions: In case 8, multiple areas of consolidation and randomly distributed nodules were found on postmortem CT (Fig. 6). These findings were quite distinct from typical postmortem changes such as hypostasis, and the autopsy revealed pneumonia. Uncharacteristic or atypical postmortem changes on postmortem CT should be closely examined because these findings can indicate antemortem pathology such as inflammation, tumors, or other lesions.
