摘　　要：目的探讨儿童肌纤维瘤的临床、影像及病理表现。方法回顾性分析经病理证实的31例肌纤维瘤患者资料,观察其影像特征性表现。结果31例中,28例以皮下无痛性包块就诊,单发28例,多发3例;5例伴钙化,13例伴囊变,12例伴包膜,增强扫描肿块呈轻中度渐进性强化8例,明显均匀/欠均匀强化11例(明显周边强化5例),2例无明显强化;其中皮下型26例,主要表现为皮下类圆形肿块,密度/信号均匀或欠均匀,强化以轻中度渐进性强化或明显强化为主。骨内型3例,主要表现为膨胀性骨质破坏,无骨膜反应及硬化边,密度/信号均匀伴明显强化。内脏型2例,主要表现为团块状明显不均匀强化肿块影。结论肌纤维瘤影像表现较具特征,特别是皮下型及骨内型,与病理具有较高一致性,术前影像学检查可清晰显示病灶的大小、数目、强化及有无内脏受累等信息。Objective To investigate the clinical,imaging,and pathological manifestations of myofibroma in children.Methods The data of 31 patients with myofibroma confirmed by pathology were analyzed retrospectively,and the imaging features were observed.Results Among the 31 cases,28 cases were treated with subcutaneous painless mass.There were 28 cases of single lesions and 3 cases of multiple lesions.There were 5 cases with calcification,13 cases with cystic degeneration,and 12 cases with capsules.The enhanced scan showed mild to moderate progressive enhancement in 8 cases,obvious uniform/uneven enhancement in 11 cases(obvious peripheral enhancement in 5 cases),and no obvious enhancement in 2 cases.Among them,26 cases were subcutaneous type,mainly manifested as subcutaneous round mass,with uniform or uneven density/signal,and the enhancement was mainly mild to moderate progressive enhancement or obvious enhancement.There were 3 cases of intraosseous type,mainly manifested as expansive bone destruction,without periosteal reaction and sclerotic edge,with uniform density/signal and obvious enhancement.There were 2 cases of visceral type,mainly with obvious uneven mass enhancement.Conclusion The imaging findings of myofibroma are characteristic,especially the subcutaneous and intraosseous types,which are highly consistent with pathology.Preoperative imaging examination can clearly show the size,number,enhancement and visceral involvement of the lesions.
