[edit] Discussion of Faceless kidney

  • The term faceless kidney was originally reported as a CT sign of duplicated collecting system.
  • In this setting, faceless refers to the appearance of the kidney on a CT section obtained at a level between duplicated collecting system elements; at this level, the kidney is entirely filled by normal renal parenchymal tissue, thus lacking the typical familiar signature of central renal sinus structures and sinus fat.
  • Use of the term has been broadened to include any process that obliterates the anticipated sinus appearance of the kidney. Thus, edema from inflammatory conditions or a more sinister infiltrative process such as lymphoma or transitional cell carcinoma may render the kidney faceless.
  • The familiar "face" should always be present, regardless of the imaging technique used.
