IMAGING FEATURES: 

Mammography

Mammography findings are nonspecific and usually negative. On the other hand, we can occasionally see microcalcifications and asymmetric density in mammography [1,3] (Fig. 2).

Ultrasonography

Ultrasonographic findings of juvenile papillomatosis are characteristic, but they are nonspecific due to these findings also seen other mastopathic and fibrous conditions of the breast. At ultrasonography, juvenile papillomatosis appears as ill-defined, hypoechoic heterogeneous mass and contains multiple small cysts mainly at the borders of the lesion [1,5] (Fig. 3). Cysts are smaller than 2 cm [1]. Also, ultrasonography can detect microcalcifications in the lesion [1]. Radiologists can make a mistake because of its cystic pattern, and it can be supposed fibrocystic changes in the breast. In our experience, radiologists pay attention to this situation, and they suspect when they see cystic mass in patients who do not have fibrocystic breast pattern.

Magnetic Resonance Imaging:

T1 weighted images show hypointense lobulated lesion. Post-contrast series, we observed that contrast-enhanced hyperintense lesion with benign enhancement profile in a dynamic sequence. [5] In our one case, we also see the malign enhancement profile. So that, enhancement profile is not a confidential finding (Fig. 4).

T2 weighted images show hyperintense numerous small internal cysts [5] (Fig. 5).
