ABSTRACT
In this study we analyse the value of high frequency ultrasound as diagnostic tool in non-palpable breast nodules (NPBN). We selected 121 women with NPBN revealed by ultrasound (US). The size of the nodules varied from 3 mm to 32 mm. Women with NPBN detected by US underwent sonographically-guided fine-needle aspiration biopsy (FNAB) and/or histological examination. Based on the US examination findings, the disease was diagnosed as malignant in 6 cases, as benign in 90, and in 28 cases it was unclassified. 15 patients underwent surgery. In 8, the disease was histopathologically confirmed as carcinoma (US 2 unclassified), 7 were benign lesions. US with FNAB as tool in diagnosing NPBN is an accurate technique for distinguishing between benign and malignant NPBN observable sonographically.
