The renal sinus is a cavity in the epicentre of the kidney communicated to the perinephric space and bordered laterally by the renal parenchyma.


It has different kind of constituents (Fig. 1):


  1. Excretory system (pelvis, major and minor calyces of the collecting system).

  2. Vessels (major branches of the renal artery and vein).

  3. Nerve fibers of the autonomic nervous system.

  4. Lymphatic channels.

  5. The rest is filled with adipose tissue (main component) and varying quantities of fibrous tissue.


Therefore, various pathologic conditions can occur.


The spectrum of renal sinus lesions can be divided in benign and malign. Alternatively, the abnormalities can be classified in either from the sinus itself or as an extension of other pathologies.


Some of these entities are frequently seen in the daily practice, such as renal sinus cysts, lipomas or urothelial tumors.


But there are other atypical pathologies that must be considered.


We will analyse the radiological appearance of these typical and atypical scenarios through a number of different cases seen in the Abdominal Radiology Department of our hospital, Hospital Vall d'Hebron de Barcelona.
