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.

Dilatation of right heart in 50-year-old deceased man (case 17).CT scan obtained 17 hours and 18 minutes after death shows dilatation of right heart (A, arrows). Although this is known to be normal postmortem change caused by blood congestion, it became clear with in autopsy that finding in this case was caused by pulmonary veno-occlusive disease. Other lesions related to this disease are also present: pulmonary artery dilation (B, arrows) and pulmonary edema (C). CT = computed tomography

Figure 15: Dilatation of right heart in 50-year-old deceased man (case 17).CT scan obtained 17 hours and 18 minutes after death shows dilatation of right heart (A, arrows). Although this is known to be normal postmortem change caused by blood congestion, it became clear with in autopsy that finding in this case was caused by pulmonary veno-occlusive disease. Other lesions related to this disease are also present: pulmonary artery dilation (B, arrows) and pulmonary edema (C). CT = computed tomography

Mentions: In case 17, we diagnosed pulmonary veno-occlusive disease on autopsy, which is a rare disease and was not suspected on postmortem CT. On postmortem CT, the right heart dilatation was more prominent than usual for a normal postmortem change (Fig. 15A), and pulmonary artery dilation (Fig. 15B) and pulmonary edema were present (Fig. 15C). In hindsight, if these findings were comprehensively evaluated, then pulmonary veno-occlusive disease may have been diagnosed on postmortem CT.
