Validity of Ultrasound in Diagnosis of Breast Mass in Relation with Fine Needle Aspiration Cytology.
Pak J Med Health Sci Jan ;12(3):1272-4.

Aim: To evaluate the validity of ultrasound in patients with breast mass Methods: This cross-sectional study was conducted at Radiology Department Combined Military Hospital, Quetta from March 2007 to November 2007. Fifty cases of diagnosed breast mass referred by clinicians were included. Ultrasound finding of breast mass was done and then correlated to fine needle aspiration cytology. The sensitivity and specificity was determined. Results: There were 32 (64%) cases of benign and 18 (36%) of malignant on ultrasound. Out of benign lesions, only 2 were actually malignant on fine needle aspiration cytology. Thus a total of 20 (40%) were proved to be malignant and 30 (60%) lesions were benign. The sensitivity of benign lesion is 88.88%, specificity 93.75% and overall accuracy rate was 92%. Conclusion: Ultrasound of breast is an easily available diagnostic modality in evaluating breast lumps. It is non- invasive cheap and cost-effective investigation. Its diagnostic role is further increased when combined with clinical and physical evaluation followed by fine needle aspiration cytology. This will relieve the anxiety of patients and will reduce the number of biopsies.
