AUGMENTATION MAMMAPALSTY - NORMAL AND ABNORMAL FINDINGS WITH MAMMOGRAPHY AND ULTRASOUND

A retrospective review of 133 patients who had undergone augmentation mammoplasty (n = 122), reconstructive mammoplasty (n = 10), and silicone injections (n = 1) was undertaken to establish the normal appearance of various types of implants, to establish a range of normal variations (wrinkles, valves, minor bulges), and to recognize true implant complications (collapse of a saline prosthesis, leakage of silicone gel, capsular contracture, capsular calcification, and deformities). The detection and evaluation of breast parenchymal abnormalities in the presence of a radiopaque implant are more difficult, and frequently ultrasound (US) or special mammographic views in conjunction with physical examination are required. Coned-down compression spot views are suggested for asymmetric opacities or ill-defined mammographic masses, and magnification views are recommended for microcalcifications: Both should be obtained with the Eklund implant displacement technique. Tangential or other special views combined with US are best for the evaluation of palpable abnormalities and suspected silicone implant rupture.
