Revisiting the canonical definition of heat hematoma: A rare case of postmortem subdural heat hematoma.

Heat hematoma is generally recognized as a postmortem heat-induced artifact in extradural spaces found in burned bodies. Conversely, subdural hematoma in charred bodies is more indicative of antemortem trauma. Here, we present a rare case of a subdural heat hematoma in forensic practice. The subdural hematoma was found in a charred body that was determined to be dead before the fire without findings of antemortem head injury. Furthermore, the detailed determination and formation mechanism of this subdural heat hematoma are discussed. With this rare case, we propose a reconsideration of the canonical definition of heat hematoma. This report envisions benefitting forensic pathologists facing similar cases.
