Sonographic Evaluation of Congenital Muscular Torticollis: A Case Study in Morphologic Asymmetry and Fibromatosis Colli
Lydia Mooney
Congenital Muscular Torticollis (CMT) is a prevalent pediatric musculoskeletal condition characterized by the shortening and fibrosis of the sternocleidomastoid (SCM) muscle, often presenting clinically as a palpable neck mass and restricted cervical range of motion. While the physical presentation can be alarming to caregivers, distinguishing the benign "pseudotumor" of infancy (Fibromatosis Colli) from malignant differentials such as rhabdomyosarcoma or neuroblastoma is critical.
