Figure 4 A 36-year-old female with a pathologically proven chromophobe renal cell carcinoma LX-4211 in the left kidney on a coronal contrast-enhanced computed tomography image. The large well-circumscribed solid tumor (arrow) shows a hypoattenuating central stellate scar ...

An important imaging characteristic is the signal intensity appearance of the tumor on T2 weighted MRI. Most papillary RCCs demonstrate low T2 signal intensity (Figure ?(Figure6A6A)[11,20,53,54,62,63]. In contrast, RG-6016 nmr most clear cell RCCs show high T2 signal intensity (Figure ?(Figure7A7A)[11,53,54,62,63] while the signal intensity of chromophobe RCCs has yet to be formally profiled in great detail. Oliva et al[63] evaluated the T1 and T2 signal intensity of 49 RCCs (28 clear cell and 21 papillary) and correlated the findings with pathology. The authors found that while the T1 signal intensity of both subtypes was similar, the neoplasms could be discriminated on the basis of the T2 signal intensity with papillary RCC showing an average mean signal intensity ratio of 0.67 �� 0.2, and clear cell RCC showing an average mean signal intensity ratio of 1.41 �� 0.4 (P ALK presence of blood degradation products (e.g., hemosiderin or ferritin), fibrosis or a high nucleus-to-cytoplasm ratio[64-66].
