Abstract

The pseudocapsule of renal cell carcinoma (RCC) appears as a low-intensity band or rim on magnetic resonance (MR) images. The frequency of its appearance differed on T1- and T2-weighted images. In our group of 19 RCC (in 18 patients), it appeared on 26.3% of T1-weighted images and on 57% of T2-weighted images. The pathology of the pseudocapsule on MR is its thickness and composition. On T1-weighted images, the appearance of the pseudocapsule is mainly related to the fibrous element, and on T2-weighted images to the fibrous element and compressed renal parenchyma.

肾细胞癌(RCC)的假包膜在磁共振(MR)图像上表现为低强度带或边缘。其在T1和t2加权图像上出现的频率不同。在本组19例RCC(18例患者)中，它出现在26.3%的t1加权图像和57%的t2加权图像上。MR上假包膜的病理表现是其厚度和组成。在t1加权图像上，假包膜的外观主要与纤维成分有关，在t2加权图像上，假包膜的外观主要与纤维成分和压缩的肾实质有关。
