A curious autopsy case of a car crash in which self-strangulation and lung collapse were found: a case report.

A curious autopsy case following the car crash of a 20-year-old male, in which self-strangulation and lung collapse were observed, is presented. His motor vehicle had crashed into a restaurant as a result of self-strangulation using an electrical cord wound four times around his neck. At autopsy, we found small rupture holes of spontaneous bullae in both lung apices, which had probably taken place upon collision during driving, petechial hemorrhages in the face skin and the absence of severe injuries. Since it seemed unlikely that the small holes in both lung apices caused fatal pneumothorax instantly, the cause of his death was judged to be asphyxia due to self-strangulation. It is not clear whether the self-strangulation was suicidal or autoerotic, because neither traces of suicidal intent nor circumstances suggesting either of them were disclosed.
