Abstract:
Objective To improve understanding of the varied, especially atypical mammographic appearances of breast infiltrating lobular carcinoma(ILC). Methods We retrospectively studied 28 ILC (27 patients) mammographic appearances and correlated with the clinical examination, ultrasonographic(US) findings.Results ①The most frequent mammographic finding was an uncalcified mass (13), followed by a mass with calcifications (5), architecture distortion was seen in 4 lesions, two lesions appeared indistinct calcifications. Pleomorphic microcalcifications, focal asymmetric density were 1 respectively, negative mammogram was in two cases. ②Eighteen lesions appeared a mass with or without calcifications on mammogram. Of them, 5 lesions appeared irregular shape. The mass with indistinct margins and spiculated borders were 9 and 6 lesions respectively. ③Seven lesions appeared subtle features, such as architecture distortion (4), indistinct calcifications (2) and focal asymmertric density (1). ④The sensitivity of mammographic detection was 86%(24/28), clinical examination was 64%(18/28), US was 85% (17/20). The sensitivity could be improved to 96%(27/28) by the use of integrated mammography, US, and clinical examination.Conclusion The irregular mass with indistinct or spiculated margins is the predominant mammographic sign in ILC. Atypical features, such as architectural distortion etc are frequently findings. The combination of mammography, ultrasonography and clinical examination is effective to detect ILC.
