Pseudoangiomatous stromal hyperplasia: imaging findings with pathologic and clinical correlation

AJR Am J Roentgenol. 2010 Oct;195(4):1036-42. doi: 10.2214/AJR.09.3284.


Objective: The purpose of this article is to describe the imaging characteristics of pseudoangiomatous stromal hyperplasia, where the primary histologic component was pseudoangiomatous stromal hyperplasia.

Conclusion: The tumoral form of pseudoangiomatous stromal hyperplasia is rare. The most common mammographic and sonographic finding is a circumscribed mass. Its appearance on MRI is nonspecific, but it may present as clumped nonmasslike persistent enhancement on contrast-enhanced imaging. Biopsy guided by MRI may be necessary to confirm the diagnosis.
