Abstract: Thoracic Outlet Syndrome (TOS) describes a variety of symptoms
caused by the compression of the neurovascular structures in the
cervicoaxillary region as they leave the thorax toward the upper limbs. Causes
of TOS are vascular and neurogenic, with neurogenic symptoms being the most
common presentation (95% of patients). Symptoms related to neurogenic TOS
include intrinsic hand muscle and thenar region atrophy and weakness, as well
as medial hand and forearm numbness, which are all suggestive of lower trunk
involvement. This condition is very rare in the pediatric population. We are
reporting a case of true neurogenic TOS caused by a fibrotendinous band in an
adolescent with bilateral cervical ribs who was submitted for surgical
treatment at the right side.
