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).
目的
本研究的目的是在随访CT扫描中评估复发性腹膜后脂肪肉瘤的CT特征和生长速率。
结论
腹膜后脂肪肉瘤常在初次手术切除后2年内无症状复发，通常在6个月至2年内。复发性脂肪肉瘤的CT特征与初始表现相似；复发性脂肪肉瘤生长迅速，平均肿瘤体积倍增时间为98天（范围46 - 151天；中位数104天）。
