Anubha Wadhwa MD, Presenter: Nothing to Disclose

Mary Beth Gonyo MD, Abstract Co-Author: Nothing to Disclose

The main causes of missed cancers on mammography are dense breasts, subtle asymmetries, slow developing densities and poor positioning or technique.False negative ultrasound may be related to detection errors or interpretation errors, especially with isoechoic masses, nearly circumscribed masses or subtle areas of architectural distortion, This is a quiz based presentation reviewing cases of missed breast cancer on mammography and ultrasound and understanding radiologic pathologic correlation. 1. Old comparison mammograms are our best friend in mammography. Comparison with at least two or three prior mammograms is necessary, especially to identify subtle changes and developing densities. 2. Isoechoic masses and subtle areas may be missed on ultrasound if proper ultrasound parameters are not used and adjusted during the exam. 3. It is important to have a good quality control program and a good audit system in every breast imaging section.

1. Quiz based presentation of various causes of undetected cancers on mammography and identification of learning points from each case. 2. Cases of missed cancers on ultrasound. Understanding mammographic-sonographic correlation and correlation of ultrasound with clinical findings. 3. Radiologic-Pathologic correlation: Identification of discordant results on biopsy.
