Craniocerebral trauma - Congruence between post-mortem computed tomography diagnoses and autopsy results: A 2-year retrospective study

Abstract: Computed tomography (CT) has been used routinely at the Department of Forensic Medicine, University of Copenhagen since 2002. A retrospective study was performed in order to correlate CT-scan based diagnoses of cranial and cerebral lesions with macroscopic autopsy diagnoses in 56 cases. The CT-scans were performed by a forensic pathologist. They were obtained by using two different CT-scan protocols. The results showed correct skull fracture diagnoses in 34/56 cases. Fractures were diagnosed partially (9) or missed totally (13) on CT-images in 22 cases. The agreement for fracture diagnoses of the anterior, medial and posterior cranial fossae was 20%, 52% and 60%, respectively. Fractures involving bilateral bones were diagnosed correctly more frequently. The diagnostic agreement regarding brain injuries varied from 0% to 79%. Both the autopsy-reports and CT-scan descriptions need to be standardized in order to secure more exact comparisons in the future. [Copyright &y& Elsevier]
