RationaleOnly a few cases of accidental deaths due to speargun injuries are reported in the literature. Murder or suicide cases are even rarer.Patient ConcernsA 59-year-old male with a history of major depression and previous suicide attempts, was found, still alive and conscious, with a spear in his mouth and a fishing speargun a few meters away. The spear then penetrated the cranium and crossed the entire left cerebral hemisphere.DiagnosesThe patient underwent a retrograde removal of the spear. During the surgery, there was a massive encephalic bleeding. After about 2 days of coma, brain death was confirmed. An autopsy was performed to determine the cause of death.InterventionsThe scalp presented hemorrhagic infiltrates in the left parieto-temporal region. There were an acute subdural hematoma and subarachnoid hemorrhage. At the opening of the lateral ventricles a massive fronto-parieto-temporal hematoma was evident. The skull base had a massive hemorrhagic infiltration and a circular fracture of about 0.5 cm in diameter, due to the penetration of the spear. The hard palate showed a circular solution of continuity with net margins whose diameter was consistent with the size of the spear.OutcomesThe cause of death was attributed to the traumatic cranial-encephalic lesions due to the speargun shot in the mouth.LessonsThe investigation into unusual cases of death constitutes a complex matter and requires a careful evaluation on the part of the forensic pathologist. A differential diagnosis may be necessary in order to rule out simulated suicide/homicide. In this particular case, the analysis of the scene of the self-suppression event and available circumstantial information, the evaluation of clinical data, the complete autopsy and the comparison between the injuries of the victim and the characteristics of the weapon used led to the confirmation of the suicidal nature of the death.
