Résumé
Breast ultrasound can image several different types of breast conditions, including both benign [non-cancerous] and malignant [cancerous] lesions. Ultrasound is frequently used to evaluate breast abnormalities that are found with screening mammography or diagnostic mammography or during a physician performed clinical breast exam. This study was conducted with the aim of investigate ultrasonographic features in differentiate benign from malignant breast masses and whether this distinction could be definite enough to obviate biopsy. Fifty four Sudanese ladies with breast nodules were sonographically classified as benign and malignant masses according to their different sonographic features which are: character, internal echogenicity, margins, sonographic artifacts [posterior echo]. Sonographic classifications about the nature of the lesions were compared with fine needle aspiration biopsy [FNAB] findings. Sonographic features that characterize suspicious breast nodules as benign were [cystic, solid and complex] character, [Isoechoic, hypoechoic and Hyperechoic] internal echogenicity, [smooth] margins and [posterior acoustic enhancement] as posterior echo artifact whiled sonographic features of suspicious malignancy nodules were [solid] character, [hypoechoic] internal echogenicity, [irregular] margins and [shadowing] as posterior echo artifact. These obtain results about the characteristics sonographic features and the natures of breast nodule were confirmed as accurate results by biopsy. Findings indicate that specific sonographic features can be helpful in differentiate benign from malignant breast[s] lesions, also sonography can be use widely and accurately so to prevent unncecessary biopsies
