Abstract
|
|
|
Fibromatosis colli is a unique mass of sternocleidomastoid muscle. Which usually presents in neonatal period and disappears within one year of age. The diagnosis of this disease is not difficult with the findings of ultrasound and the unique
clinical
behavior of the mass.
The purposes of this study are to evaluate the detailed sonographic features of fibromatosis colli and to find the value of color Doppler studies on the initial evaminations and the follow-up of the patients.
Twenty-four patients who were diagnosed as fibromatosis colli by the clinical history and ultrasound examination were studied. Among them. 11 patients underwent follow-up stdueis including color Doppler imaging. We evaluated the size. Shape and
echogenicity of the mass. The sonographic features and the findings at color Doppler imaging of 11 follow-up studies were compared with those of the initial examinations.
Most of the masses were identified at about 3 wecks of age. The mean size of the masses was 30×10×15mm. Most of the masses were round(n=13, 54%) or fusiform (n=8.33%) in shape. The echogenicity of the mass was iso(n=15.63%) or slightly
hyperechoic(n=9, 37%) to that of the surrounding muscles. All 8 cases examined with color Doppler showed branching pattern of arterial signal within the mass at the initial examination. On the follow-up studies, most of the lesions decreased in
size and
increased in their echogenicity. There was no color Doppler signal on the follow-up study in 7 out of 8 patients in whom both the initial and the follow-up color Doppler imagings were performed.
In conclusion. The sonographic findings of fibromatosis colli were more cormplicated than those described by previous literatures and color Doppler examination could give more information about this disease especially on follow-up of larger
series
is
required to know the practical significance of the results of follow-up studies.
