Abstract:
PURPOSE: To document the radiologic characteristic findings of atypical ductal epithelial hyperplasia, we analyzed film mammographic, ultrasonographic, and MRI findings of our cases. MATERIALS AND METHODS: We analyzed 23 cases of surgically proven ADH, excluding carcinoma in ipsilateral breast. Presence and pattern of neodensity, microcalcification, and architectural distortion were reviewed on mammography. Echo pattern and ductal parenchymal morphology were analyzed on ultrasonography, and enhancement speed and pattern analysis were performed on MRI. RESULTS: On film mammography, ADH showed tendency of neodensity(10 of 23 cases), m icrocalcification(11 of 23 cases), with less parenchymal distortion of surrounding structures(7 of 23 cases). On ultrasonography, ADH was demonstrated as inhomogenous to intermediate echoic nodule(16 of 20 cases) with ragged border(19 of 20 cases), however, its boundary was thin or nearly absent(16 of 20 cases), and showed smooth ductal echography(11 of 20 cases). Gd-DTPA contrast dynamic MR study showed relatively slow and less enhancement in 4 out of 5 cases, with progressive inclination of the speed curve of enhancement in later period of dynamic study. CONCLUSION: Multimodality image approach is needed for better evaluation of ADH, however, excisional biopsy is recommended for confirmative diagnosis and proper treatement.
