FIBROMATOSIS COLLI

A BENIGN CERVICAL PSEUDOTUMOR AND ITS ASSOCIATION WITH ANOMALIES IN THE FIRST RIB

Abstract

Fibromatosis colli (FC) is a rare benign disease in which there is proliferation of the fibrous tissue of the sternocleidomastoid muscle (SCM), with complications during childbirth or genetic factors in neonates. The objective of the present study is to show a case of CF in an adult after a contact injury between a rudimentary rib and the SCM muscle. Ultrasound (US) as a complement to the clinic is the method of choice for diagnosis and to prevent any unnecessary invasive intervention, with conservative treatment with anti-inflammatories, physiotherapy, chiropractic and, as a last resort, surgery, if symptoms worsen during follow-up or occurrence of complications.
