Abstract
Imaging studies of 29 patients with pathologically proven superior sulcus carcinoma of the lung were reviewed. Posteroanterior and lateral chest radiographs at the time of presentation demonstrated an asymmetric apical cap in 55% and an apical mass in 45%. Additional views of the chest were sometimes useful; however, the lordotic view was frequently misleading. Accurate assessment of the local extent of disease was best provided by computed tomography. Needle biopsy was the most efficacious nonsurgical method of establishing a pathologic diagnosis.
