Sonoelastography has been utilized to evaluate various myopathies. However, the benefits of adding sonoelastography to conventional ultrasound (US) in patients with congenital muscular torticollis are unclear.
To evaluate the value of adding sonoelastography to conventional US in patients with congenital muscular torticollis.
This study included 27 infants clinically diagnosed with congenital muscular torticollis and 17 healthy infants who underwent conventional US and sonoelastography. The echogenicity of the sternocleidomastoid muscle was assessed as isoechoic, heterogeneous, hyperechoic or hypoechoic compared with normal muscle. The thickness of the involved and contralateral sternocleidomastoid muscles was measured. Elastographic findings were scored from 1 (soft) to 3 (hard) by two independent radiologists.
The sternocleidomastoid muscle thickness, difference and ratio between involved and normal sternocleidomastoid muscle thickness, and elastographic score differed significantly between the patient and control groups. Of the 27 patients, 11 had isoechoic, 5 had heterogeneous and 11 had hyperechoic muscles. Congenital muscular torticollis patients with isoechoic muscle showed significantly higher elastographic scores than the control group, but there were no other significant differences by conventional US.
Adding sonoelastography to conventional US is helpful for the diagnosis of congenital muscular torticollis, especially in patients with isoechoic sternocleidomastoid muscle.
超声弹性成像已被用于评估各种肌病。然而，在先天性肌性斜颈患者中，将超声弹性成像添加到常规超声（US）中的益处尚不清楚。
评估在先天性肌性斜颈患者中添加超声弹性成像对常规 US 的价值。
本研究纳入了 27 例临床诊断为先天性肌性斜颈的婴儿和 17 例健康婴儿，这些婴儿均接受了常规 US 和超声弹性成像检查。与正常肌肉相比，胸锁乳突肌的回声强度评估为等回声、不均匀、高回声或低回声。测量受累和对侧胸锁乳突肌的厚度。两位独立的放射科医生对弹性成像结果进行评分，从 1（软）到 3（硬）。
患侧和健侧胸锁乳突肌厚度、受累和正常胸锁乳突肌厚度之间的差异和比值以及弹性成像评分在患者组和对照组之间差异均有统计学意义。27 例患者中，11 例为等回声，5 例为不均匀回声，11 例为高回声。等回声的先天性肌性斜颈患者的弹性成像评分明显高于对照组，但常规 US 无其他显著差异。
将超声弹性成像添加到常规 US 中有助于先天性肌性斜颈的诊断，特别是在胸锁乳突肌等回声的患者中。
