MR appearance of the pseudocapsule of renal cell carcinoma and its pathologic basis.
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.
