Fig. 10. Non-hemorrhagic hyperdense fluid in colon in 72-year-old deceased woman (case 12).

CT scan obtained 1 hours and 48 minutes after death shows hyperdense content in colon (arrow) similar to case 11. However, this material was not hemorrhagic on subsequent autopsy. It was unclear based on patient's medical history whether she was administered oral contrast medium or other oral medication, such as laxative. Residual contrast material is also observed in kidneys of cases 12 and 16 because contrast-enhanced CT was performed immediately before death. CT = computed tomography
