MR Imaging and Spectroscopic Findings of Primary Angiosarcoma of the Breast: A Case Report

Angiosarcoma is a rare, malignant tumor of the breast. MR spectroscopy and a new breast MR imaging technique called MR angiography were used to study a case of multifocal primary angiosarcoma of the breast. The mass was isointense on the T1-weighted images and it was hyperintense on the T2-weighted images. Early fast enhancement and draining vessels with a washout curve were revealed by the dynamic enhancement. The MR spectroscopy did not show a choline peak.
