The authors present a case of intrathoracic prolapse of the scapula af
ter anterolateral thoracotomy. Although shoulder deformity and weaknes
s have been reported after thoracotomy, intrathoracic scapular displac
ement has not previously been described. Debilitation and steroid ther
apy may have contributed to weakness of the chest wall. Computed tomog
raphy of the thorax was essential in making the diagnosis.
