Abstract
Breast cancer is the most common malignancy affecting women in many parts of the world. Its early detection has, therefore, become necessary to reduce morbidity and mortality from the disease.Mammography and ultrasound play an important role in early detection and diagnosis of breast cancer as they are the most common imaging modalities used for screening and diagnosing different breast abnormalities.Micro calcifications are a common finding in mammography and usually require invasive procedures to diagnose or exclude malignancy.This study included 30 women patients with breast microcalcifications in mammography.in our study, we evaluated the following mammographic findings (breast density, asymmetry, mammographic mass, suspicious microcalcifications, skin thickness ,nipple retraction & axillary adenopathy ).complementary ultrasound was done for all patients.Of the 30 patients, 23 patient (76.6%) with fine pleomorphic microcalcifications, 4 patients (13.3%) with fine linear branching microcalcifications, 3 patients (10%) with fine linear calcifications . 40 % of patients showed mammographic masses (3.3 % Oval shaped equal density mass, 33.3% irregular non circumscribed high dense mass, 3.3 % multiple oval shaped non circumscribed low dense masses)By complementary ultrasound, 25 patients showed breast masses 80% with irregular shape, 20 % with oval shaped .96% with non circumscribed margin, 4% with circumscribed margin, 96% hypoehoeic, 4% heterogenous. 56% showing multiple masses. according to histopathology the most common type was invasive ductal carcinoma.Our results reported that sonomammography has sensitivity of 100%, specificity 33%, positive predictive value (PPV) 93%, negative predictive value (NPV) 100% and diagnostic accuracy 93%In conclusion:Proper correlation between ultrasound and mammography improves sensitivity and accuracy for detecting breast malignancy.
