Abstract：
UNASSIGNED: Fibromatosis colli (FC) is a rare pseudotumor of the sternocleidomastoid muscle with an incidence of 0.4%, generally diagnosed using ultrasound between 2 and 4 weeks of age. This is an important entity considering the clinical concerns it causes due to its appearance as a cervical mass with torticollis. Few magnetic resonance imaging (MRI) descriptions of its appearance have been made, with the existing reported cases being sporadic. We aim to provide a thorough description of this paediatric entity.
UNASSIGNED: We conducted a retrospective study by searching our hospital\'s database for previous cases of FC where an MRI had been performed. We found six cases of FC where an MRI had been performed. Of these cases, five out of six were contrast-enhanced. We examined the MRIs to be able to discern and describe the MRI characteristics of FC.
UNASSIGNED: We found that FC presents a T1 signal isointense to the muscle, a T2 signal hyperintense to the muscle, a variable diffusion signal and a thick enhancing peripheral ring after contrast administration.
UNASSIGNED: Our results match what has been reported in the literature to date regarding the MRI signal of FC, confirming previous reports. However, we provide new data regarding the characteristic appearance post-enhancement, which was previously unreported.
UNASSIGNED: The MRI characteristics of FC have rarely been described, with only a few isolated case reports in the medical literature. We review the current literature, describe the key MRI characteristics of the pathology, and provide the most thorough description to date.

摘要：
■结肠纤维瘤病（FC）是一种罕见的胸锁乳突肌假瘤，发生率为0.4％，通常在2至4周龄之间使用超声诊断。考虑到由于其表现为伴有斜颈的宫颈肿块而引起的临床关注，这是一个重要的实体。很少对其外观进行磁共振成像（MRI）描述，现有报告的病例是零星的。我们的目标是提供这个儿科实体的全面描述。
■我们进行了一项回顾性研究，在我们医院的数据库中搜索了以前进行过MRI的FC病例。我们发现了6例进行了MRI的FC。在这些案件中,六分之五是对比增强的。我们检查了MRI，以能够辨别和描述FC的MRI特征。
■我们发现FC向肌肉呈现T1信号等强度，对肌肉的T2信号强度过高，在对比剂给药后,可变的扩散信号和厚的增强外周环。
■我们的结果与迄今为止文献中关于FC的MRI信号的报道相符，确认以前的报告。然而,我们提供了有关增强后特征外观的新数据，这是以前没有报道的。
■FC的MRI特征很少被描述，医学文献中只有少数孤立的病例报告。我们回顾了当前的文献，描述病理学的关键MRI特征，并提供迄今为止最彻底的描述。
