ABSTRACT
True neurogenic thoracic outlet syndrome (TOS) is an uncommon disorder despite of be a frequent reason for referral to the EMG laboratories. We describe the second case in the literature of true TOS in a competitive swimmer with progressive weakness and severe atrophy of the left thenar eminence. EMG showed lower trunk plexopathy. X-ray and MRI of the cervical spine and brachial plexus were normal. Surgical exploration evidenced the lower trunk retracted and pulled by a fibrous band. It was excised and neurolysis of the plexus was done with gradual improvement of function. We discuss the possible pathophysiology of this association.
RESUMO
A síndrome do desfiladeiro torácico verdadeiro é condição incomum, apesar de ser uma razão freqüente de encaminhamento aos laboratórios de eletroneuromiografia. Nós descrevemos o segundo caso na literatura desta doença rara em um nadador competitivo com fraqueza e atrofia severa da eminência tenar esquerda. A ENMG mostrou plexopatia do tronco inferior. O RX e as ressonâncias magnéticas da coluna cervical e do plexo braquial foram normais. Exploração cirúrgica mostrou o tronco inferior tracionado por uma banda fibrosa. Ela foi ressecada e procedeu-se a neurólise do plexo com melhora gradual da função. Nós discutimos a possível fisiopatologia desta associação.
