ABSTRACT
PURPOSE : This study was performed to evaluate the mammographic and sonographic features of mass-likefibrocystic disease of the breast to differentiate from other breast mass. MATERIALS AND METHODS : Weretrospectively analyzed characteristics mammographic(16 cases) and sonographic findings(39 cases) ofhistopathologically proven mass-like fibrocystic disease of the breast in 39 patients. RESULTS : Of 16 patientswith mammogram, mass-like fibrocystic disease of the breast was round shape in 12 cases, high density in 14 cases.The margin of the mass was well marginated in 8 cases, poorly marginated in 8 cases. The calcification within themass was not detected in 13 cases. In 39 patients with sonogram, mass-like fibrocystic disease of the breast wasmostly ovoid shape in 24 cases, hypoechoic in 23 cases, with homogenous internal echo in 36 cases, well defined in28 cases, and with equivocal posterior shadowing in 26 cases. The T/AP ratios of the mass was not less than 1.5 in29 cases. The bilateral edge-shadowing of the mass was not noted in 24 cases. CONCLUSION : Characteristic findingsof the mass-like fibrocystic disease of the breast are round shape, high density, well defined mass on mammograrnand ovoid shape, homogeneous internal echo, well marginated mass on sonogram which were similar to those in otherbenign lesion. Mass-like fibrocystic disease, which in a frequent cause of breast lumps, should be included in thedifferential diagnosis of breast mass with benign mammographic and/or sonographic findings.
