Case Discussion
Fibromatosis colli typically presents with a neck swelling at 1-2 months after birth, most commonly as a result of a complicated vaginal delivery and always came with head tilt to the affected site and neck mass.
Ultrasound imaging is the imaging modality of choice in diagnosing fibromatosis colli.
