Characterization of Malignant Breast Lesions Using Ultrasonography and Breast Imaging Reporting and Data System

Abstract

Breast masses have become common in women; such masses may pose a potential threat to women especially when it belongs to breast cancer. Breast cancer is one of the leading causes of cancer death in women worldwide. This is a descriptive hospital-based study, conducted at National Ribat University hospital, the study aimed to characterize Breast malignant lesions using breast Imaging Reporting and Data System (BIRAD) and ultrasonography. 71 suspected patients were enrolled in the study; all of them were scanned with ultrasound machine (Philips / Neusoft) with 10 MHZ probe. BIRADS category lesions were diagnosed in all 71 women after extensive conventional imaging work-up. The result of the study showed that 49 patients were found to be positive after conducting histopathology examination, indicating a sensitivity of 97% and a positive predictive value of 96%. Specificity was found to be 95% and the negative predictive value was found to be 95% as well. 23 (30.99%) of participants showed no solid mass while 48 (69.01%) showed a solid mass by using Ultrasonography. 39 patients (54.93%) showed hypoechoic echo pattern, while 3 (4.23%) showed an anechoic echo pattern. Isoechoic and complex echo patterns were 1 (1.41%) and 5 (7.04%), respectively. Regarding shape; 31 (43.66%) showed irregular lesion. Furthermore, Margin of the lesions of patients was found to be speculated in 18 (25.35%), while 13 patients (18.31%) showed micro-lobulated margins. The study indicated that the assessment of breast lesions with the use of the Breast Imaging Reporting and Data System ultrasound lexicon showed a significant diagnostic reliability for description of breast cancer.
