Mammography and sonomammography are two widely used modalities for evaluation of breast masses. The relative risk of malignancy in breast masses and prognostication is assessed by using the BIRADS lexicon proposed by the American college of radiology (ACR). The aim of our study was to determine the efficacy of mammography and sonomammography in evaluation of women presenting with breast lump. Our study included 147 women presenting to our institute with complaints of breast lump. X-ray mammography and sonomammography evaluation of these patients yielded 155 masses. Histopathological confirmation of diagnosis by biopsy / excision of the mass was done. Mammography had a sensitivity of 89%, specificity of 80 % and a PPV of 69%. Sonomammography evaluation had 95 % sensitivity, 79% specificity with PPV and NPV being 68% and 97 % respectively. In conclusion, the sensitivity of mammography is higher in symptomatic women than screening mammography. Sonomammography performed better than mammography in lesion characterization in symptomatic women. It helped in differentiation of solid from cystic lesions thus eliminating the necessity of follow up. Sonomammography is a useful adjunct to mammography in evaluation of dense breasts.
