[Directed ultrasonography in the diagnosis of abscesses and cysts of the breast].

Based on 1,301 examinations the author refers to the contribution of aimed ultrasonography in the diagnosis of abscesses and cysts of the breast. The aimed ultrasonography is a simple, fast and exceptionally sensitive and reliable method of examination in their detection and differentiation from solid homomorphcus processes depicted on mammograms. Its importance grows in the examination of fibroglandular tissue which cannot be differentiated on the mammogram. It reduces or completely suppresses invasive methods of examination, enables aimed diagnostic and therapeutic puncture and enables a long-term observation of abscesses and cysts of the breast without any risk.
