Hepatic trauma generally presents with four types of injuries: hepatic lacerations, blunt hepatic injuries, hepatic contusions, and hepatic penetrating injuries, which have different manifestations on CT. 1. Hepatic laceration. In imaging, it often shows branching or linear ill-defined low-density shadow, and if acute blood clot is present, it may show high-density shadow. 2. Blunt hepatic injury. In contrast, it often shows stellate or radial fissures. Within 1 week, the lesions have clearer boundaries but lower density, and after about 2 to 3 weeks, the boundaries of the lesions begin to be unclear, and the width of the fissures begins to become narrower, and ultimately an isodense shadow is presented. 3. Hepatic contusion. It usually shows a lesion that is lower than the density of liver parenchyma, its boundary is unclear, and if it is accompanied by infarction together, there is an irregular or wedge-shaped low-density shadow. 4. Hepatic penetrating injury. Pseudobiliary cysts are usually seen on imaging and usually present as a limited hypodense shadow, mostly days to weeks after the trauma. If hepatic trauma is suspected, patients should consult the doctor in time, complete relevant examinations, make a clear diagnosis, and then take appropriate treatment plan.
