Imaging findings of chest wall lesions on breast sonography

Objective. The purpose of this presentation is to illustrate the sonographic findings of chest wall lesions that were depicted on breast sonography. Methods. Chest wall lesions detected during breast sonography were collected and reviewed retrospectively. Results. The sonographic findings of normal chest walls and various pathologic chest wall lesions, including inflammatory lesions, benign neoplasms, and malignant neoplasms, are discussed. Conclusions. Familiarity with normal sonographic anatomy and chest wall lesions could be helpful in differentiating a chest wall lesion from a breast lesion and in showing whether the origin of any palpable breast lump is in the breast parenchyma or the chest wall on breast sonography.
