Background
In this paper,
we would like to first define the term of renal pseudotumor to avoid confusion and misinterpretation.
Renal pseudotumors is defined as a real or simulated renal mass,
radiologically resembling neoplasm,
but histologically consisting of normal renal parenchyma.
Numerous entities are capable of simulating a renal neoplasm.
Some of them,
such as renal cysts or abscesses,
can be diagnosed radiologically with some ease,
allowing for conservative treatment.
However,
there are rare renal lesions that despite the efforts to characterize it accurately,
can be indistinguishable from a renal neoplasm.
In these cases,
given the diagnostic uncertainty and concern about the possibility of malignancy,
it is inevitable to perform a biopsy or resection of the lesion.
Among these entities we highlight: abnormalities of renal development,
infectious diseases,
inflammatory or granulomatous diseases and renal vascular alterations (Table 1).
