We report a case of hypothermic death that resulted from extreme freezing, with characteristic postmortem computed tomography (PMCT) findings. A 75-year-old man died in a deeply frozen state. In PMCT, there was a lack of increase in the bilateral lung-field attenuation. Urinary retention, with a hypodense area of frozen urine, was observed in the bladder. Changes that appeared to involve the crystallization of serum in frozen blood were observed in the aorta. Based on the scene and his circumstances, it was speculated that he died of hypothermia. Present case and our review revealed that although PMCT findings from hypothermic death that resulted from deep freezing are very rare, the characteristic PMCT findings may help determine the cause of death.
我们报告一例因极度冷冻导致体温过低死亡的病例，并伴有特征性的死后计算机断层扫描（PMCT）表现。一名75岁男性死于深度冷冻状态。在PMCT检查中，双侧肺野衰减未见增加。膀胱内观察到尿潴留，伴有冷冻尿液的低密度区。主动脉内观察到似乎与冷冻血液中血清结晶有关的变化。根据现场情况和他的境遇，推测他死于体温过低。本病例及我们的文献回顾显示，尽管深度冷冻导致体温过低死亡的PMCT表现非常罕见，但特征性的PMCT表现可能有助于确定死因。
