Abstract:
PURPOSE: To evaluate differential points of patterns of clustered microcalcification between malignant(n=17) and benign(n=46) lesions on mammogram MATERIALS AND METHODS: We retrospectively and prospectively evaluated mammograms of surgically confirmed 63 patients showing clustered microcalcifications. Area, density, number, size, shape of calcification were evaluated along with associated mass and parenchymal distortion. RESULTS: Malignant calcifications were more variable in size(14/17, 77% vs 25/46, 53%) and shape(l 1/17, 64. 8% vs 13/46, 28.2%) than benign counterparts. Pepper, fine granular, branching, comma, tadpole and wormiform calcification were observed in malignant lesion with statistical significance. The malignant calcifications showed more faint(12/17, 70.5% vs 23/46, 50%), irregular margin(17/17, 100% vs 19/46, 42%) and they were usually associated with parenchymal distortion(16/17, 94% vs 9/46, 20%) and ill-defined masses(10/17, 58.9% vs 12/46, 26.1%). CONCLUSION: Clustered microcalcifications with variable size and shape, faint or irregular margin, parenchymal distortion, ill-defined masses seen on mammography, suggest malignancy.
