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.
