Abstract:
Objective To investigate the appearance of solid papillary carcinoma (SPC)of breast on MRI and mammography correlated with histopathological features.Methods Fifteen patients with breast SPC diagnosed from January 2011 to January 2013 were enrolled.Their MR and mammography imaging findings were retrospectively reviewed,15 patients had MRI and 11 patients had mammography.The correlation between pathological characteristics and imaging findings was made.Results All the SPC displayed a solid-papillary growth pattern together with Luminal A type,and 14 cases showed neuroendocrine markers.On mammography,only three cases showed the abnormality.The most frequently seen MRI feature was its location in the posterior of areola (11 cases),ductal ectasia on T1WI (11 cases) and high signal intensity on T2WI.The enhancement patterns included non-mass-like enhancement (10 cases),mostly manifested as ductal with clumped enhancement (5 cases) and segmental with pebble shaped enhancement (4 cases),whereas mass-like enhancement (5 cases) exhibited as annular heterogeneous enhancement.Conclusions SPC is difficult to detect on mammography,but the MRI features may suggest its distinct histological type as papillary tumor.The ultimate diagnosis still depends on histopathology and immunohistochemical results.
