The Corona Mortis, a Frequent Vascular Variant Susceptible to Blunt Pelvic Trauma: Identification at Routine Multidetector CT

The corona mortis variant can be identified on routine contrast-enhanced multidetector CT scans in about one-third of patients. Thin (1.25-mm) CT reconstructions demonstrate this variation much more frequently than 5-mm-thick images. This suggests that the corona mortis may be prospectively identified at contrast-enhanced multidetector CT in pelvic trauma patients and help guide subsequent endovascular embolization. However, further study in the trauma population is necessary to confirm this.
