title: Analysis of the mammographic and sonographic features of pseudoangiomatous stromal hyperplasia.
abstract: 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.
