Imaging features of primary breast sarcoma.

Objective: This purpose of this study is to describe the imaging findings in patients who presented with a diagnosis of primary breast sarcoma.

Materials And Methods: A search was performed of the pathology database at a single institution for patients with a histopathologic diagnosis of primary breast sarcoma or pure sarcomatoid carcinoma and who underwent preoperative mammography, sonography, or MRI. Patients with malignant phyllodes tumors were excluded.

Outcome analysis of 9-gauge MRI-guided vacuum-assisted core needle breast biopsies.

Objective: The purpose of this article is to correlate 9-gauge MRI-guided vacuum-assisted breast biopsy with surgical histologic findings to determine the upgrade rate and to correlate the frequency of MRI-guided vacuum-assisted breast biopsy cancer diagnosis with breast MRI indications and enhancement characteristics of targeted lesions.

Materials And Methods: A database search was performed of all MRI-guided vacuum-assisted breast biopsies performed from January 1, 2005, to September 31, 2010. The breast MRI indications, history, age, risk factors, lesion size, enhancement characteristics, and pathologic diagnoses at MRI-guided vacuum-assisted breast biopsy and at surgery were documented.
