Congenital bilateral sternocleidomastoid contracture: a case report.

Unilateral sternocleidomastoid muscle contracture causing torticollis and other secondary deformities such as facial scoliosis, plagiocephaly and scoliosis of cervical spine are well known. The aetiology and pathogenesis is still intriguing. Although unilateral contracture of sternocleidomastoid is seen quite often, bilateral sternocleidomastoid contracture is almost unheard of. A review of the English literature revealed no cases of bilateral congenital sternocleidomastoid contracture being reported. We present a case report of a 19-year-old girl with congenital bilateral sternocleidomastoid contracture.
