Foreign body granulomas of the breast presenting as bilateral spiculated masses

In Asia, mammography following the injection of foreign materials into the breasts for cosmetic augmentation is frequently seen and diagnosis based on the typical radiologic findings is straightforward. We report the unusual radiologic findings in two patients with foreign body granulomas caused by injected foreign materials and discovered incidentall y during screening work up. The mammographic findings were bilateral, hyper dense, spiculated masses, with occasional microcalcification, and at sonogr aphy, markedly hypoechoic, spiculated solid masses, located near the pector alis muscle and partly extending into it, were observed. These radiologic f indings mimicked malignancy.
