Primary angiosarcomas of the kidney are very rare but highly aggressive tumors showing poor prognosis. We present a case of primary renal angiosarcoma occurring in a 60-year-old man with left flank pain. CT images depicted a huge exophytic mass (14 cm in diameter) in the left kidney, exhibiting central extensive hemorrhage or necrosis without contrast enhancement. The mass showed centripetal peripheral nodular enhancement on dynamic contrast-enhanced CT images. We suggest its inclusion in the differential diagnosis of cases of hemorrhagic renal tumors with prominent vasculature.
原发性肾血管肉瘤非常罕见，但具有高度侵袭性，预后较差。我们报告一例发生在一名60岁男性身上的原发性肾血管肉瘤，该患者有左侧腰痛症状。CT图像显示左肾有一个巨大的外生性肿块（直径14厘米），中央有广泛出血或坏死，无对比增强。在动态对比增强CT图像上，该肿块呈向心性外周结节状强化。我们建议将其纳入对具有显著血管系统的出血性肾肿瘤病例的鉴别诊断中。
