| Fibromatosis colli is a unique mass of sternocleidomastoid muscle, which usually presents in neonatal periodand disappears within one year of age. The diagnosis of this disease is not difficult with the findings ofultrasound and the unique clinical behavior of the mass. The purposes of this study are to evaluate the detailedsonographic features of fibromatosis colli and to find the value of color Doppler studies on the initialexaminations and the follow-up of the patients. Twenty-four patients who were diagnosed as fibromatosis colli bythe clinical history and ultrasound examination were studied. Among them, 11 patients underwent follow-up studiesincluding color Doppler imaging. We evaluated the size, shape and echogenicity of the mass. The sonographicfeatures and the findings at color Doppler imaging of 11 follow-up studies were compared with those of the initialexaminations. Most of the masses were identified at about 3 weeks of age. The mean size of the masses was30x10x15mm. Most of the masses were round (n=13,54%) or fusiform (n=8,33%) in shape. The chogenicity of the masswas iso- (n=15,63%) or slightly hyperechoic (n=9,37%) to that of the surrounding muscles. All 8 cases examinedwith color Doppler showed branching pattern of arterial signal within the mass at the initial examination. On thefollow-up studies, most of the lesions decreased in size and increased in their echogenicity. There was no colorDoppler signal on the follow-up study in 7 out of 8 patients in whom both the initial and the follow-up colorDoppler imagings were performed. In conclusion, the sonographic findings of fibromatosis coli were morecomplicated than those described by previous literatures and color Doppler examination could give more informationabout this disease especially on follow-up studies. A long term follow-up of larger series is required to know thepractical significance of the results of follow-up studies. |
