Two deaths occurred after ingestion of cyanide-containing Extra-Strength Excedrin capsules. Cranial CT scans obtained within 3 hr of each patient's collapse showed diffuse cerebral swelling and loss of gray-white differentiation. Most diffuse cerebral insults (hypoxia, ischemia) do not show such changes so soon after injury. The early onset of diffuse cerebral edema with loss of gray-white differentiation may be a clue to the diagnosis of acute cyanide poisoning.
两名患者在摄入含氰化物的强效埃克塞德林胶囊后死亡。在每位患者晕倒后3小时内进行的头颅CT扫描显示弥漫性脑肿胀且灰白质分界消失。大多数弥漫性脑损伤（缺氧、缺血）在损伤后这么短时间内不会出现这样的变化。伴有灰白质分界消失的弥漫性脑水肿的早期出现可能是急性氰化物中毒诊断的一条线索。
