Systems:
A faceless kidney refers to one in which the normal appearance of the renal sinus on cross-sectional imaging is absent. It was initially described as a sign of duplication of the collecting system 1 (a slice obtained between the two collecting systems will not demonstrate the normal components of renal parenchyma, fat and collecting system). The term has been used more widely for any cause of absence of this normal appearance.
Pathology
Etiology
Causes include:
- renal duplication
- urothelial tumors
- renal lymphoma
- inflammation/infection
- renal hilum AVM
