Usefulness and limitation of postmortem computed tomography in bath-related death: Four case reports

Publication date: Available online 9 May 2017 Source:Journal of Forensic Radiology and Imaging Author(s): Satoko Mishima, Hideto Suzuki, Yoko Nishitani, Tatsushige Fukunaga Bath-related death occurs relatively frequently in Japan; however, there is room for improvement in the investigation of such deaths. Here, we describe four autopsy cases of bath-related death (one case of drowning; one of drowning under the influence of drinking; and two cases of sudden cardiac death without drowning) in which postmortem computed tomography (PMCT) was performed before autopsy. Based on analysis of autopsy and PMCT findings of these cases, we further discuss the utility and limitation of PMCT when applied to bath-related death. Comparison of the autopsy findings and PMCT findings between the cases suggests that combinations of several PMCT findings in bath-related death cases (e.g., signs suggestive of overinflated lungs, hemodilution, and excessive water intake in the gastrointestinal tract) can serve to distinguish drowning cases from non-drowning cases. Many bath-related deaths have been reported to have drowning signs at autopsy, although elderly victims with cardiovascular diseases tend to be diagnosed as death due to disease without employing PMCT or autopsy. Therefore, this case series suggests that implementation of PMCT in bath-related death might prevent underestimation of drowning as a cause of death. Although PMCT alone has several limitations, such as inability to evalua...
