Objective:
The purpose of this study was to evaluate the CT features and growth rates of recurrent retroperitoneal liposarcoma on follow-up CT scans.
Conclusion:
Retroperitoneal liposarcoma frequently recurs asymptomatically within 2 years, usually within 6 months-2 years, of the initial surgical resection. The CT features of recurrent liposarcoma are similar to those of the initial manifestation; recurrent liposarcoma shows rapid growth, with a mean tumor volume doubling time of 98 days (range, 46-151 days; median, 104 days).
