Renal sinus pathologies, including lipomatosis and cysts, require differentiation from other conditions. Advanced imaging like CT and MR are crucial for evaluating complex renal sinus diseases and staging tumors.

Area of Science:

  • Radiology
  • Urologic Imaging
  • Pathology

Background:

  • The renal sinus can be affected by primary lesions or secondary involvement from surrounding structures.
  • Common benign lesions include lipomatosis and cysts, necessitating differentiation from more significant pathologies.

Purpose of the Study:

  • To review the spectrum of pathologic conditions affecting the renal sinus.
  • To highlight the role of various imaging modalities in characterizing these lesions.

Main Methods:

  • Review of imaging findings for diverse renal sinus pathologies.
  • Discussion of characteristic appearances on excretory urography, ultrasonography, computed tomography (CT), and magnetic resonance (MR) imaging.

Main Results:

  • Renal vascular lesions (aneurysms, fistulas) mimic other conditions on urography but are identified with advanced imaging.
  • Renal parenchymal tumors (renal cell carcinoma) and pelvic tumors (transitional cell carcinoma) can involve the renal sinus.
  • Observation of renal sinus fat is key for detecting small tumors and staging.

Conclusions:

  • Accurate diagnosis of renal sinus lesions relies on understanding their origin and characteristic imaging features.
  • Multiplanar CT and MR imaging are essential for evaluating the extent of complex renal sinus disease.
