Fibromatosis Colli: What is the Role of Ultrasound?

Abstract

Fibromatosis colli is a rare, usually self-limiting condition caused by a benign tumor in the sternocleidomastoid muscle. The tumor occurs most often during infancy and can be clinically associated with torticollis. Accurate diagnosis of fibromatosis colli is important to avoid unnecessary invasive interventions. Ultrasound is considered the radiological examination of choice for diagnosis, as it is noninvasive, inexpensive, and has 100% sensitivity. We discuss the case of a one-month old child who presented with a head tilt and had ultrasound imaging that favore diagnosis of fibromatosis colli.
