摘要
目的观察腹、盆腔促纤维组织增生性小圆细胞瘤(DSRCT)的 CT 表现特征。方法对经病理证实的4例腹、盆腔 DSRCT 患者的 CT 资料做回顾性分析。结果 4例病变共同 CT 表现包括:腹、盆腔巨大软组织肿块,边缘多个分叶,多累及腹、盆腔脏器浆膜及腹膜,与周围器官关系密切,但其来源不清,常见大小不一出血坏死区,增强扫描呈轻到中度不均匀强化。结论腹、盆腔 DSRCT的 CT 表现具有一定特征,对临床诊治有一定帮助。
Objective To investigate the CT features of desmoplastic small round cell tumor （DSRCT） occurred in abdomen and pelvis. Methods The CT images of 4 patients with pathologically proven DSRCT occurred in abdomen and pelvis were retrospectively analyzed. Results The CT features common to the 4 DSRCT in abdomen and pelvis were as follows： the lobulated soft-tissue masses were very large; the masses often involved omental and serosal surfaces of abdomen and pelvis organ and had close relationship to the surrounding organs; the originating site of the tumors were not apparent; intratumoral hemorrhage or necrosis were often present; and contrast-enhanced CT scan showed mild to medium heterogeneous enhancement. Conclusion The CT features of DSRCT in abdomen and pelvis are rather specific and can provide helpful information to the clinical diagnosis.
