Abstract

PURPOSE: To evaluate the relationship between sonographic findings and clinical outcome of fibromatosis colli.
MATERIALS AND METHODS
Sonograms and medical records of thirty nine infants with fibromatosis colli were retrospectively reviewed for sonographic features (location, shape, AP dimension of the lesion, lesion-SCM ratio and echopattern) and follow-up data (duration of treatment, functional and clinical outcome after physical therapy).
RESULTS
Lesions were located in either the lower two third (19cases) or lower one third (20cases) of the sternocleidomastoid muscle. Thirteen cases (33%) involved only the sternal portion of the sternocleidomastoid muscle while no cases involved only the clavicular portion of the sternocleidomastoid muscle was seen. Twenty-six (67%) cases involved both sternal and clavicular portions. Thirty-four infants had a mass in the sternocleidomastoid muscle while 5 infants had only diffuse muscle enlargement without a definite mass. The echogenicity of the lesion were hyperechoic in 20 cases, isoechoic in 9, hypoechoic in 3 and patchy echotexture in 7 cases. The duration of treatment was shorter, and functional result was more satisfactory in the group with the diffuse muscle enlargement. The longer duration of treatment was required in patients with a larger size, larger L-S (lesion-SCM) ratio and patchy echo-texture of the lesion.
CONCLUSION
Sonographic evaluation of fibromatosis colli provided a good predictive guideline of the duration of treatment and result after physical therapy.
