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.
在大多数患者中，除了那些脂肪极少的患者外，通过CT扫描（使用适当的窗口设置）可以看到肾筋膜。CT证实了当前的解剖学概念；然而，与文献中所示的插图相反，它清楚地表明肾前间隙通常仅存在于腹膜后器官的水平。病变会使该间隙扩张。虽然在正常尿路造影上看到肾筋膜可能提示肾脏疾病，但CT扫描上肾筋膜变薄并无病理意义。增厚是非特异性的：它不是肿瘤的特征性表现，也无助于区分胰腺炎和肿瘤。另一方面，没有筋膜增厚可能有助于排除邻近病变向肾脏的蔓延。
