Fibromatosis colli, Newborn, Torticollis


A 16-day-old male was observed at the Emergency Department for a right cervical mass noticed on the same day by the parents, with no other associated symptoms. He was a fullterm child, delivered by vacuum extraction, with an uneventful perinatal period.
At the time of physical examination, a cervical mass was palpable in the inferior portion of the right sternocleidomastoid muscle, in association with ipsilateral torticollis.
Cervical ultrasound revealed a fusiform thickening of the sternocleidomastoid muscle, with well-defined, hypoechoic margins, confirming the diagnosis of fibromatosis colli.
Parents were instructed to adopt positioning measures and physical therapy was initiated, with clinical resolution by seven months of age.
Fibromatosis colli is the most severe presentation of congenital muscular torticollis. Although typical clinical findings usually enable the diagnosis, cervical ultrasound is useful to confirm muscular origin of the mass.
Torticollis in the opposite direction of the mass, spinal deformities, abnormal eye movements, or other abnormal neurological findings
