Sternocleidomastoid (SCM) pseudotumors, also known as fibromatosis colli or congenital torticollis, are painless benign neck lumps found in newborns. Whilst unilateral cases are relatively common, bilateral SCM pseudotumors are a rare phenomenon with only a handful of cases reported internationally. We present the case of a 5-week-old infant who was brought to the emergency department with painless, bilateral, palpable anterior neck masses following a slightly traumatic but otherwise uncomplicated spontaneous delivery. An ultrasound scan of his neck revealed well-defined soft tissue lesions within both of the SCM muscles. He was subsequently diagnosed with bilateral SCM pseudotumors. This case emphasizes the importance of considering this entity as a differential diagnosis in infants presenting with bilateral palpable neck masses.
胸锁乳突肌（SCM）假瘤，也称为纤维瘤性斜颈或先天性斜颈，是在新生儿中发现的无痛性颈部良性肿块。虽然单侧病例相对常见，但双侧SCM假瘤是一种罕见现象，国际上仅报道了少数病例。我们报告一例5周大婴儿，在经历轻微创伤但无其他并发症的自然分娩后，因无痛性双侧可触及的颈部前肿块被带到急诊科。对其颈部进行超声扫描发现双侧胸锁乳突肌内有边界清晰的软组织病变。随后他被诊断为双侧SCM假瘤。该病例强调了在出现双侧可触及颈部肿块的婴儿中将此病症作为鉴别诊断的重要性。
