PURPOSE: The object of this study was to describe the sonographic findings of mass-forming pseudoangiomatous stromal hyperplasia. MATERIALS AND METHODS: A retrospective review of ten patients with breast sonography and five patients with mammography who had pseudoangiomatous stromal hyperplasia presenting as a breast mass. All cases were confirmed by surgical biopsy. RESULTS: The mean age of the 10 patients was 41 years old (21 -51) and the mean mass size was 4.7 cm (2.5-10). On sonography, all lesions were oval shaped and well circumscribed, hypoechoic masses. Nine of the ten lesions presented with homogeneous internal echogenicity and one lesion with a complex heterogeneous pattern with a small internal cyst. A mammogram was performed in five patients and all lesions were oval, well circumscribed, high density masses. CONCLUSION: Sonographic findings of mass-forming pseudoangiomatous stromal hyperplasia of the breast were similar with those of other benign breast masses, so biopsy should be performed for diagnosis.
