Search and removal of radioactive seeds: another application of postmortem computed tomography prior to autopsy

Abstract

We herein introduce 3 cases illustrating a new application for pre-autopsy postmortem computed tomography (PMCT). In all 3 cases, there was insufficient background information about the victims provided to the forensic pathologists' department. PMCT showed metallic particles in the prostate gland, an indication of metallic seeds containing radioactive isotopes. In 2 of 3 cases, migrated seeds were also detected by CT imaging in the lungs and the heart. Also in 2 of 3 cases, authorities reinvestigated the victim's history before autopsy was completed, which resulted in following appropriate procedure for dealing with the seeds. Although all 3 cadavers were cremated after autopsy, the International Commission on Radiological Protection (ICRP) discourages cremation for deaths soon after radioactive seeds implantation to prevent air pollution by radioactive isotopes in the ash. Our opinion from the present cases is that pre-autopsy PMCT can be recommended for use by forensic pathologists and guidelines for investigating deaths after permanent brachytherapy should include how to deal with cadavers when medical history is limited.

Nasal Septum Defects Detected on Postmortem Computed Tomography

“…The PMCT as a noninvasive supplement to traditional autopsy can reveal small but relevant findings, which may go undetected during the external examination of the body or during autopsy. [17][18][19][20][21][22] A nasal septum defect may be such a finding, as clinical examination of the nose and the nasal cavities may be difficult, especially in cases of advanced decomposition with maggots' infestation or cases of severe facial trauma. The PMCT can easily and quickly reveal septal defects and allows further detailed investigation of its characteristics, like its edges' morphology and the presence of insects in the region.…”
