The CT and MR findings in 2 patients with surgically proven splenic angiosarcoma are presented. Two distinctive radiologic and pathologic patterns were observed: total tumor replacement of the spleen with preservation of normal contour or multiple nodular masses in the spleen. The various findings on CT and MR imaging reflected the hemorrhagic nature of the lesions with increased iron content. MR imaging appeared to be superior to CT in demonstrating these features. In the case of focal lesions, radiologic differentiation from lymphoma or metastasis was impossible.
本文报告了2例经手术证实的脾血管肉瘤患者的CT和MR表现。观察到两种不同的影像学和病理学模式：脾脏完全被肿瘤替代但轮廓保持正常，或脾脏内出现多个结节状肿块。CT和MR成像的各种表现反映了病变的出血性质以及铁含量增加。在显示这些特征方面，MR成像似乎优于CT。对于局灶性病变，无法通过影像学与淋巴瘤或转移瘤进行鉴别。
