目的探讨腹盆腔促纤维组织增生性小圆细胞瘤(desmoplastic small round cell tumor,DSRCT)的CT表现。方法回顾性分析5例DSRCT的典型病例,并结合相关文献复习,探讨其CT表现。结果 4例表现为腹盆部多发大小不等的肿块,最大的肿块呈囊实性,位于小肠系膜,无明显钙化;1例表现为双侧卵巢巨大类椭圆形囊实性肿块,密度不均匀,边界不清,周围见转移灶。5例患者肿瘤标记物CA125分别为172.20 U/ml,158.40 U/ml,126.70 U/ml,117.60 U/ml,96.90 U/ml(正常值<35 U/ml)。结论 DSRCT CT表现多样,结合实验室检查对早期诊断有一定价值。
Objective To investigate the CT manifestations of desperado small round cell tumor (DSRCT) in the abdomen and pelvic cavity. Methods A retrospective analysis of 5 cases of DSRCT typical cases, combined with review of relevant literature, to explore its CT performance. Results Four cases showed multiple masses in the abdomen and pelvic region. The largest mass was cystic, located in the small mesenteric, without calcification. One case showed a large oval cystic solid mass in both sides of the ovary. The density was not. Uniform, unclear boundaries, see metastases around. The tumor markers CA125 in 5 patients were 172.20 U/ml, 158.40 U/ml, 126.70 U/ml, 117.60 U/ml, 96.90 U/ml (normal value <35 U/ml). Conclusion The DSRCT CT findings are diverse, combined with laboratory tests have some value for early diagnosis.
