Subtentorial Meningioma Misdiagnosed as Cerebral Hemorrhage in Postmortem Computed Tomography Imaging: A Case Report

This report presents a case of a 52-year-old man who had a traffic accident and died later. External examination could not determine the cause of death. Approximately 3 weeks later, an autopsy was performed. Postmortem computed tomography was performed before the autopsy. Postmortem imaging was interpreted to show hemorrhage beneath the tentorium, and the C5 to C6 (the fifth and sixth cervical vertebra) disc space was widened. During the autopsy, a cervical spinal cord injury was confirmed. However, a meningioma was found under the tentorium instead of a hemorrhage. There are a number of reasons that include postmortem changes that affected the virtopsy diagnosis, which still needs development.
