Abstract

A malignancy is a fatal condition that could occur through various mechanisms. Forensic pathologists sometimes find unexpected findings during autopsy and post-mortem (PM) tests. Colorectal cancer is one of the leading causes of cancer-related deaths worldwide. The deceased was a 64-year-old man with a medical history of right hemicolectomy due to colon cancer approximately two years earlier. He was found dead at his home. He was admitted to the hospital due to subdural hemorrhage (SDH) two days prior to his demise and was discharged without the permission of the doctor after one day of hospitalization. An autopsy was performed within two days of his death. After gross dissection, the cause and manner of death were assumed to be SDH and unnatural death, respectively. Microscopic examination revealed fresh SDH and dural metastasis of signet-ring cell carcinoma. Furthermore, metastasis was identified in the heart, stomach, and peritoneum. Immunohistochemical examination revealed cancer cells to originate from the colon. After meticulous PM examination, including gross dissection, microscopic examination, PM computed tomography, and PM laboratory tests, the cause and manner of death were determined as SDH and natural death, respectively. This case report highlights the importance of comprehensive PM evaluation for investigating death.
