Abstract

Fibromatosis colli is a benign fibrous mass developed from the sternocleidomastoid muscle. The exact etiologies are unknown. It seems that it is due to birth trauma. Ultrasound is the diagnostic tool of choice. The treatment is based on physiotherapy.

Summary

Introduction

Fibromatosis colli has been described for the first time by the German Hulbert as tumor torticollis of the sternocleidomastoid muscle It is a benign lesion of this latter which is linked to congenital fibrosis and manifested clinically by a neck swelling and torticollis [1]. We report the case of a 2 1⁄2 months infant who is male and born at term in good general conditions He was born by caesarean section following a lack of engagement of the vertex after complete dilatation of the cervix. The mass is attached to the sternocleidomastoid muscle which is non-inflammatory It resulted a slight restriction of neck’s movement on the right side (Figure 1). A remarkable reduction in the size of the mass was observed after 4 weeks of physiotherapy It disappeared completely in 5 months which results a return to normal neck’s movement (Figure 3)
