Thoracic Computed Tomography in Superior Sulcus Tumors

Abstract

Computed tomography (CT) can be helpful in the preoperative evaluation of patients with a superior sulcus (Pancoast) tumor. The cross-sectional format and tissue resolution of CT better demonstrate the relationship of tumor to significant anterior structures (subclavian artery and vein, trachea, and esophagus) and posterior structures (chest wall and vertebral bodies) than do conventional techniques. Invasion of the subclavian vessels, mediastinum, or vertebral bodies contraindicates surgery.
