Unusual presentation of tubular breast carcinoma as non-mass enhancement

A tubular carcinoma is a rare and well-differentiated histological subtype of invasive ductal carcinoma. Its lesion is generally presented as a spiculated, solid mass on mammography, ultrasonography (US), and magnetic resonance imaging (MRI) with posterior acoustic shadowing on US. Here, we describe unusual MRI findings of focal-type clumped non-mass enhancement and type 2 kinetic curve. This tumour should be included as a differential diagnosis with focal-type clumped non-mass enhancement on MRI, because this finding can refer benign lesions like as fibrocystic changes of breast.
