Pseudoangiomatous stromal hyperplasia: imaging findings with pathologic and clinical correlation.

Abstract

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