Primary breast angiosarcoma (MRI)

Discussion:

Primary breast angiosarcoma is a rare neoplasm. (~0.04% of all breast cancers).

In this particular case is noteworthy that lesion was not detectable at the second look sonography. The patient underwent an MRI guided biopsy that resulted in a diagnosis of well-differentiated angiosarcoma.

Another interesting feature of this mass is, it demonstrates very subtle findings in T1 and STIR pre-contrast imaging. In post contrast sequences, it demonstrates an intense enhancement.

Although the tumor is well differentiated it has to be considered of aggressive nature.
