Summary
Renal pseudotumors will simulate a neoplasm on urography but are histologically composed of normal tissue. Pseudotumoral lesions of the kidney are usually discovered on urography and simulate a neoplasm, but are histologically composed of normal tissue. Various conditions such as foetal lobulation, hypertrophy of the columns of Bertin or large cloisons, nodular compensatory hypertrophy, renal sinus lipomatosis, and compression by blood vessels may simulate tumors of the kidney. It is therefore of the utmost importance to make a clear-cut diagnosis with the help of echography, CT-scan, and in some cases, arteriography.
