title: Pectus excavatum deformities simulating mediastinal masses.
abstract: Three patients with various pectus excavatum deformities in whom radiographic findings suggested hilar and mediastinal masses are presented. Computed tomography of the chest yielded valuable diagnostic information and made it possible to exclude the existence of these masses. Compression deformity of the heart and great vessels by the pectus deformity is the most likely explanation for these findings.
