Answer

Juvenile papillomatosis is an uncommon condition seen in young women. It may produce an appearance of multiple masses with marked distortion on mammograms. On MRI, this may appear as a network of enhancing, beadlike nodules that are connected by enhancing ducts. Alternatively, they may appear as a lobulated, enhancing mass with small internal cysts.
