A55-year-old woman presented with 1-year history of mass in the right breast. Incisional biopsy showed the tumor to be malignant hemangiopericytoma from its histology. The tumor showed low--intermediate density and peripheral contrast enhancement on CT, and inhomogeneous mixed-signal intensity both on T1W and T2W images, and peripheral enhancement with Gd-DTPA on MRI with no invasion of the duct.
一名55岁女性因右乳肿物1年就诊。切开活检显示，从组织学上看，该肿瘤为恶性血管外皮细胞瘤。CT显示肿瘤呈低至中等密度，周边强化；T1加权像和T2加权像均显示信号强度不均匀且混杂，MRI增强扫描钆喷酸葡胺后周边强化，且未侵犯导管。
