Abstract Hemopericardium (HP) is frequently found at autopsy, but it represents a challenge for the forensic pathologist when having to assess its etiopathological relationship in causing death, particularly in those cases where ante-mortem clinical and instrumental data are not available. The diagnosis of pericardial tamponade (PT), in fact, is based on signs, symptoms and instrumental evidence and not only on the presence of HP. Post-mortem imaging techniques are actually considered a useful and non-invasive method able to enhance traditional procedures in demonstrating critical forensic findings; consequently, post-mortem imaging methods have been widely introduced in forensic investigations. We report a case of death clearly due to PT caused by ruptured dissected aneurysm of the aorta, submitted to post-mortem CT (PMCT) and PMCT angiography prior to autopsy. PMCT imaging permitted to solve the case without performing autopsy. In the paper we identify PMCT findings suggestive of PT with the aim of verifying the possibility to use post-mortem evidence to retrospectively demonstrate an in vivo dynamic clinical condition, such as PT.
