The value of postmortem computed tomography in paediatric natural cause of death: a Dutch observational study.

BACKGROUND

Postmortem CT is a relatively new field of interest within paediatric radiology. This paper focusses on its value in cases of unexpected natural death.

OBJECTIVE

We report on an observational Dutch study regarding the value of postmortem CT in children with an assumed natural unexpected death because postmortem CT is part of the Dutch NODO (additional investigations of cause of death) procedure.

MATERIALS AND METHODS

We included consecutive children who fulfilled criteria for the NODO procedure and were therefore referred to one of the centres for the procedure. Postmortem CT was performed in all cases and skeletal survey was performed in all children ages <5 years. The cause of death was defined in a consensus meeting.

RESULTS

We included a total of 54 children (30 boys, median age 1.1 years, and 24 girls, median age 0.8 years). A definitive cause of death was established in 38 cases. In 7 cases the cause of death could be identified on postmortem CT. In 7 cases imaging findings were clinically relevant but did not lead to a cause of death. In the remaining 40 cases postmortem CT did not add to the diagnostic workup.

CONCLUSION

Our study shows that in a group of children who unexpectedly died of an assumed natural cause of death and in whom a cause of death was found at autopsy, postmortem CT detected the cause of death in a minority of cases (12.9%). In the majority of cases (74.1%) postmortem CT did not add value in diagnosing the cause of death.
