Two cases of renal leiomyosarcoma are described. At angiography both cases presented common findings consisting of: (1) central hypovascularity surrounded by peripheral tumor neovascularity and (2) oval-shaped areas that rapidly filled with contrast medium. This angiographic appearance, although not previously described in such tumors, cannot be claimed to offer a key to preoperative diagnosis because it may be found in the more common hypernephromas with central necrosis.
本文描述了两例肾平滑肌肉瘤。血管造影显示，这两例病例有共同表现：（1）中央血管减少，周围有肿瘤新生血管；（2）椭圆形区域迅速被造影剂充盈。这种血管造影表现，虽此前未在这类肿瘤中描述过，但不能作为术前诊断的关键依据，因为在更常见的伴有中央坏死的肾细胞癌中也可能出现。
