Pseudoangiomatous Stromal Hyperplasia: Imaging Findings With Pathologic and Clinical Correlation

Abstract

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.
