The Correlation of Sonographic and Histopathologic Findings in the Diagnosis of Palpable Breast Masses in Zaria.

INTRODUCTION

Presently, histology is the gold standard in definite diagnosis of breast masses. Ultrasound is a relatively cheap, non-invasive, and non-ionizing imaging modality which is widely available in most hospitals. An assessment of its accuracy in diagnosing breast masses is necessary to minimize unwarranted biopsies.

AIM AND OBJECTIVES

This study aims to correlate the ultrasonographic and histopathologic findings in the diagnosis of patients with palpable breast masses.

MATERIALS AND METHODS

This was a cross-sectional hospital-based study, which involved 100 consecutive patients who presented with palpable breast masses in Zaria. This was carried out for a period of 7 months (November 2016-June 2017). They had a clinical breast examination to identify the mass, which was then imaged and biopsied via ultrasound-guided fine needle aspiration cytology.

RESULTS

The generated data were analysed using SPSS version 23.0 (Chicago, IL, USA). There were more benign masses (63%) than malignant masses (29%). On correlating the final diagnosis of ultrasound to that of histology, it was found to have a sensitivity of 89%; specificity of 94%; positive predictive value of 89%; negative predictive value of 94%; and accuracy of 92%.

CONCLUSION

This study shows that there was a correlation between ultrasound and histology findings in differentiating between benign and malignant masses. This proves that ultrasound has a significant role to play in evaluating and diagnosing clinically palpable breast masses.
