【摘要】：目的探讨儿童韧带样纤维瘤(DT)的影像诊断价值。方法回顾性分析14例经病理证实的儿童DT的临床及影像特点。9例行CT平扫及增强扫描,2例行MRI平扫及增强扫描,3例同时行CT及MR检查。结果儿童DT主要为腹壁外型,病灶呈梭形、卵圆形,沿肌纤维间隙浸润性生长。CT平扫表现为等、稍低密度肿物,动脉期呈轻度不均匀强化,延迟扫描强化程度显著增高。MRI表现为软组织肿物,T1WI等/稍低信号,T2WI多为不均匀稍高信号,T1WI及T2WI均见索条状稍低信号,增强后不均匀强化。结论儿童DT CT/MRI表现为梭形、卵圆形沿肌肉间隙生长的软组织肿物,延迟强化明显增高;MRI能显示其中的纤维成分,其影像特征为正确诊断提供重要依据。
[Abstract]:Objective to evaluate the diagnostic value of DTI in children with desmoid fibroma. Methods the clinical and imaging features of 14 children with DT confirmed by pathology were retrospectively analyzed. Ct and Mr examinations were performed in 3 cases with MRI plain scan and contrast-enhanced scan. Results DT in children was mainly abdominal wall shape with spindle shape and oval shape. Infiltrative growth along the muscle fiber space. Ct plain scan showed iso-low density tumor, slightly uneven enhancement in arterial phase, significantly increased degree of delayed scan enhancement. MRI showed soft tissue mass. On T1WI and T2WI, most of them were inhomogeneous and slightly hyperintense. Both T1WI and T2WI showed slightly hypointensity in cord stripe. Conclusion DT CT/MRI in children is fusiform and oval soft tissue masses growing along the muscle space, and delayed enhancement is obviously increased. MRI can display the fiber components, and its imaging features provide important basis for correct diagnosis.

【正文快照】： 韧带样纤维瘤(desmoid tumors,DT)是发生于肌肉、腱膜和筋膜的纤维源性肿瘤。国外资料显示发病率占软组织肿瘤的3%,占所有肿瘤的0.03%,临床上较为少见[1]。由于对本病缺乏深刻的认识,在儿科,术前常常被误诊为血管瘤或其他恶性肿瘤。本文回顾性分析本院2007年3月至2014年1月14
