We report a case of an 89-year-old female with active extravasation and hemoperitoneum from a liver laceration demonstrated on multidetector computed tomography (CT), attributed to the use of an automated mechanical cardiopulmonary resuscitation (CPR) device. Although iatrogenic internal injuries related to manual CPR and CPR devices have previously been reported [1, 2], there has been no reported CT evidence of liver injury related to automated CPR devices to the authors' knowledge. Imaging findings of complications related to the use of automated CPR devices are important to recognize and also help explain the possible mechanisms of injury. Liver injuries with active bleeding following CPR may have devastating consequences related to hemodynamic instability and may have an increased incidence when CPR is performed using an automated chest compression device.
