[Sonographic detection of intracystic breast tumors].

While simple breast cysts account for the most common benign lesions of the breast, intracystic tumours, which most frequently occur as papillomas and papillary adenocarcinomas, are rare. In this paper we report on the clinical picture of these tumours, using our own material, and discuss the relevance of sonography in pre-operative diagnosis compared to conventional examination techniques such as mammography and pneumocystography.
