腹内侵袭性纤维瘤病影像学表现与病理相关性

摘要

Objective To investigate the CT and MRI manifestations of intra-abdominal aggressive fibromatosis and correlation with pathology.Methods The CT and MRI manifestations of 26 cases with intra-abdominal aggressive fibromatosis confirmed by pathological examination were analyzed retrospectively.Results 26 cases showed single solid mass,13 cases showed well-circumscribed and round-like,9 cases wrapped around the common bile duct,intestine or ureter,4 cases were lobulated which had unclear margin with surrounding tissues in pelvic.All the lesions displayed isodensity or slightly low density non-enhanced CT appearance,heterogenous high intensity FS T2WI,some larger tumors showed mixed signal.CT/MRI enhanced scan showed gradual enhancement in 26 cases.Conclusion Intra-abdominal aggressive fibromatosis have some certain imaging features,MRI can offer the histo logical features of tumors and have some correlation with pathology.%目的 探讨腹内侵袭性纤维瘤病(AF)的CT、MRI影像学表现及其病理学相关性.方法 回顾性研究本院26例经病理确诊的腹内AF的CT及MRI表现.结果 26例腹内AF均为单发实性肿块,其中13例肿瘤边界清楚,呈类圆形,9例包绕胆总管、肠管或输尿管生长,4例位于盆腔呈分叶状,与周围结构分界不清.CT平扫呈等低密度,T2 WI抑脂呈不均匀稍高信号,肿瘤较大时,可呈现高、等或低信号交织排列.增强扫描26例肿瘤呈渐进性强化.结论 腹内AF影像学表现有一定特征性,MRI能提供肿瘤相关组织学特征,并与病理具有一定相关性.
