Visibility and thickening of the renal fascia on computed tomograms.
The renal fascia can be seen on CT scans (using appropriate window settings) in most patients except those with very little fat. CT confirms current anatomical concepts; however, contrary to the illustrations shown in the literature, it clearly demonstrates that the anterior pararenal space normally exists only at the level of the retroperitoneal organs. A lesion would distend the space. While visualization of the renal fascia on normal urograms may be an indication of renal disease, a thin renal fascia on CT scans has no pathological significance. Thickening is nonspecific: it is not pathognomonic of tumor, nor is it helpful in differentiating pancreatitis from neoplasm. On the other hand, lack of fascial thickening may be helpful in ruling out renal extension of a neighboring lesion.
