CTICasesTraumatic IVC Tear and Retroperitoneal Hematoma
Imaging findings
CT chest and abdomen in a trauma patient shows a large retroperitoneal hematoma surrounding the inferior vena cava (IVC), with subtle contour irregularity of the infrarenal IVC. A small, minimal aortic injury (intimal tear) is also noted.
Key takeaways
Traumatic IVC injury carries high mortality. On early-phase CT, low-pressure venous injuries can be subtle and obscured by surrounding hematoma or compression. A high index of suspicion is required when a large paravalvulvar hematoma is present, necessitating delayed phase imaging.
