MRI of the Right Breast


Pear-like shaped mass between upper quadrants (56 mm), with sharp margins. The mass is hyperintense in T2 acquisitions, hypointense in T1 acquisitions. Enhancement is slightly inhomogeneous with an inner core more vividly enhancing. The lesion enhancement shows a type I curve (progressive enhancement). The lesion is hyperintense in DWI acquisitions.

Findings are quite suggestive of a benign lesion.
