Calcifications of renal masses are common. They are usually dense, partial, small, punctate, and linear opacities. Diffuse calcification is an extremely rare feature of renal masses. Generally, calcified renal cell carcinomas are hypovascular, with calcifications in the interstitium, and they also contain fibrotic capsules, necrotic areas, or hyalinization. We recently observed a renal neoplasm with diffuse calcification on CT and intermediate vascularity on angiography, which was diagnosed histologically as renal cell carcinoma, clear cell type. Interestingly, there were numerous calcific deposits within the tumor cells.
肾肿块的钙化很常见。它们通常表现为致密、部分性、小的、点状和线状的不透光区。弥漫性钙化是肾肿块极其罕见的特征。一般来说，钙化的肾细胞癌血供较少，钙化位于间质，还含有纤维性包膜、坏死区域或玻璃样变。我们最近观察到一例肾肿瘤，CT显示有弥漫性钙化，血管造影显示为中等血供，经组织学诊断为肾细胞癌，透明细胞型。有趣的是，肿瘤细胞内有大量钙化沉积。
