摘要
目的探讨促结缔组织增生性小圆细胞肿瘤影像学特征,并与病理学进行对照研究,以期提高影像学术前诊断准确性。方法回顾性分析经病理证实的9例促结缔组织增生性小圆细胞肿瘤影像学资料,9例患者术前进行了CT平扫及动态增强检查,其中1例患者在CT平扫及动态增强检查后又进行了MRI平扫及动态增强检查,9例患者影像学检查前均未进行相关治疗,最终9位患者通过手术病理证实。结果9例均为男性患者,平均年龄为21.3岁,均表现为腹、盆腔内软组织肿块影,4例肿块位于盆腔,另外5例位于腹腔内,与腹膜关系密切,其中7例肿瘤内部可见钙化,2例患者出现腹腔积液,9例肿瘤内均含有不同程度坏死,9例肿瘤动态增强呈现渐进性强化,1例MRI动态增强可见肿瘤内部不均匀强化,周边呈环状强化。结论促结缔组织增生性小圆细胞肿瘤常见于青少年男性,与腹膜、网膜及肠系膜关系密切,与周围实质脏器无明显起源关系,常规影像学术前可以提示诊断,从而更好地指导临床治疗。
Objective To investigate the imaging characteristics of desmoplastic small round cell tumor and compare it with pathology,so as to improve the accuracy of imaging preoperative diagnosis.Methods The imaging data of 9 cases of desmoplastic small round cell tumors confirmed by pathology were analyzed retrospectively.9 patients underwent CT plain scan and dynamic enhancement before operation,and one patient underwent MRI plain scan and dynamic enhancement after CT plain scan and dynamic enhancement.None of the 9 patients underwent relevant treatment before imaging examination,Finally,9 patients were confirmed by surgery and pathology.Results All the 9 cases were male,with an average age of 21.3 years.They all showed soft tissue mass shadow in abdominal and pelvic cavity.Four cases was located in pelvis,and the other 5 cases were located in abdominal cavity,which was closely related to peritoneum.Calcification was found in 7 cases,peritoneal effusion was found in 2 case,and necrosis was found in 9 cases;Nine cases of tumor dynamic enhancement showed progressive enhancement,one case of MRI dynamic enhancement showed uneven enhancement inside the tumor and circular enhancement around the tumor.Conclusion Desmoplastic small round cell tumor is common in adolescent men.It is closely related to peritoneum,omentum and mesentery,and has no obvious origin relationship with surrounding parenchymal organs.Conventional imaging can prompt diagnosis before academic.so as to better guide clinical treatment.
