Pseudoangiomatous stromal hyperplasia: mammographic, sonographic, and clinical patterns. Academic Article uri icon

Overview

abstract

  • PURPOSE: To analyze the mammographic, ultrasonographic (US), and clinical patterns of pseudoangiomatous stromal hyperplasia (PASH). MATERIALS AND METHODS: Preoperative mammographic and US images, clinical records, and histologic assessments were reviewed in seven cases of PASH as the sole component or dominant stromal component of a clinically or mammographically defined mass lesion. In five, a PASH tumor was diagnosed at image-guided 14-gauge core-needle biopsy; in two, it was diagnosed at surgical excisional biopsy. RESULTS: Four women were premenopausal, two were postmenopausal, and one 40-year-old patient had iatrogenic primary amenorrhea. Four of seven masses were palpable; three were discovered at mammography. Four masses enlarged over 6 months to 5 years. At mammography, all masses lacked calcifications; six were well defined, and one was spiculated. One was inapparent at US; the remaining six were well defined and hypoechoic. CONCLUSION: The diagnosis of this rare lesion with image-guided breast biopsy or surgical biopsy is consistent with a well-defined uncalcified mass at mammography and a solid hypoechoic mass at US, usually in a premenopausal woman.
