Analysis of the mammographic and sonographic features of pseudoangiomatous stromal hyperplasia.
OBJECTIVE
The purpose of this study was to describe the imaging findings in 149 patients with pseudoangiomatous stromal hyperplasia (PASH) who had undergone at least 4 years of clinical follow-up for detection of subsequent malignancy.


CONCLUSIONS
PASH is a common entity that presents with benign imaging features without evidence of subsequent malignant potential. At our institution, in the absence of suspicious features a diagnosis of PASH at core biopsy is considered sufficient, and surgical excision has been obviated.
