Contribution of CT in thoracic bony lesions.

Fourteen patients with bony lesions of the thoracic wall, seven benign and seven malignant, were evaluated. In lesions with an aggressive appearance on plain films, computed tomography proved to be very accurate for mapping their extent, and for evaluating adjacent organ involvement. For non-aggressive bony lesions of the chest wall, plain films are sufficient for determining the nature of the lesion.
