Congenital Torticollis with Bilateral Sternocleidomastoid Muscle Contracture

Congenital muscular torticollis is a common musculoskeletal disorder characterized by the shortening of the sternocleidomastoid muscle, thus leading to an ipsilateral tilt of the head and contralateral rotation of the face. Most of the congenital muscular torticollis is ipsilateral. Bilateral congenital muscular torticollis is extremely rare. Congenital muscular torticollis is known to be associated with several musculoskeletal and neurologic disorders including brachial plexus injury. Therefore, early diagnosis and intervention are crucial for the treatment and prevention of associated complications. Here, we report a case of a 1-month-old infant with bilateral congenital muscular torticollis suspicious of Erb-Duchenne palsy.
