Comparison of Benign and Malignant Microcalcifications
Abstract
- PURPOSE
To evaluate morphologic characteristics of the microcalcifications on mammography that were confirmed pathologically.
MATERIALS AND METHODS
Forty five cases of microcalcifications on mammography (fifteen cases of benign lesion, thirty cases of maiignancy) were retrospectively reviewed.
RESULTS
The number of microcalcifications within 1 cm2 were more than 5 in 22 cases (73%) of 30 malignancy and less than 5 in 11 cases (73%) of 15 benignity. The heterogeneity of microcalcifications were seen in 26 cases of malignancy (87%) and the homogeneity of microcaicifications were 11 cases of benignity (73%). The morphologic characteristics of the microcalcifications were linear-V shape in 9 cases (30%), punctate shape in 8 cases (27%), fine stippled shape in 7 cases (23%), and round dot shape in 6 cases (20%) of malignancy and, round dot shape in 11 cases (73%), punctate shape in 2 cases (13%), and linear-V shape in 2 cases (13%) of benignity.
CONCLUSION
Numerous irregular microcalcifications that are heterogenous in size and morphology were strong indicators of malignancy.
